What is Pheromone?

Have you ever met someone who is mysteriously, insanely attractive? Then you may be dealing with something known as ‘Pheromones.’

Now you might be curious about Pheromones? Hence, we will cover all the essential points about Pheromone in this article.

Of course, we are not going to discuss about human pheromones, rather, insect pheromones that deal with insects. This is very general article about pheromones. At ChemHub, we are making a few pheromones targeting some insects. Please visit our pheromone page at www.chemhub.com in the product category.

What are pheromones?
Pheromones are a single or small group of molecules that send messages between creatures of the same species, causing them to modify their behavior.

Pheromones are often simply one component of a broader collection of odorants released by an insect or mammal, and others have no noticeable fragrance. Nevertheless, odorants play a critical part in insect communication, and as we’ll see, they employ a wide range of chemical substances.

Animal pheromones

Animals secrete pheromones to trigger various behaviors, including raising the alarm, sexual arousal, warning another animal to back off, signaling a food trail thanks to their enhanced senses, and vomeronasal organ. The first pheromone, known as bombykol, is said to have been discovered in 1959. Bombykol is thought to be released by female moths to attract males.

Discovery of Pheromones
Pheromones were discovered by accident in the 18th century. Bonnet, a French ecologist, discovered the ant trail. He set up a table with an ant colony on one end and a little pile of sugar on the other.

He noticed that ants leaving the colony crossed the table to the sugar mound, picked it up, and carried it back to the colony. The ants followed a set path back and forth, with no deviations.

According to a study conducted by French biologist Pierre Bonnet, when he rubbed his finger over a line of ants, the ants came to a halt and searched the rubbed region. Then, they tapped their antennae on the ground while waving them in the air. Bonnet believed that the ants’ path was a trail of chemicals that they could detect and follow.

Types of Pheromones

Alarm pheromones
Alarm pheromones are volatile chemicals produced by clonal or social insects in reaction to a disturbance. Monoterpenes, sesquiterpenes, and short-chain aliphatic hydrocarbons are some of the signals that can be detected. They are less specific than other types of pheromones and typically contain combinations of chemicals.

Releaser pheromones
Releaser pheromones are a type of pheromone that may be used to
Pheromones that change the recipient’s behavior are known as releaser pheromones. Some creatures, for example, employ potent attractant chemicals to attract mates from two kilometers or more away. This sort of pheromone evokes a fast response in most people, but it degrades quickly.

Trail pheromones

Trail pheromones are a multipurpose chemical secretion that guides individuals of the same species to a food source while also acting as a territorial mark in the form of an allomone to creatures from other species. Trail pheromones are usually mixed with secretions from many exocrine glands to achieve better specificity.

Trail pheromone deposition is one of the essential elements that explain the effectiveness of social insect communication today. Moreover, it is one of the fundamental chemical signaling systems many social insects rely on.

Signal pheromones
Signal pheromones are a type of pheromone that is used to Short-term effects, such as the release of neurotransmitters that activate a reaction, are caused by signal pheromones. For example, the chemical Gonadotropic releasing hormone (GnRH) acts as a neurotransmitter in rats to cause lordosis behavior.

Epideictic pheromones
Epideictic pheromones are mainly used to indicate where female insects lay their eggs. Food pheromones are often associated with trail pheromones; they are associated with species that employ volatile hydrocarbons to steer their actions toward breeding to survive.

Information pheromones
Pheromones that indicate an animal’s identification or territory are known as information pheromones. For example, cats and dogs deposit chemicals in and around their territory, which signals that the occupier is there to other species members.

Modulator pheromones
Pheromones that modulate or synchronize biological activities are known as modulator pheromones. They’re most commonly detected in sweat. Scientists discovered that when put on the top lip of females, they became less nervous and calmer in animal trials. The monthly cycle of a woman may be affected by modulator hormones.

Aggregation pheromones
Aggregation pheromones are used for predator defense, partner selection, and mass attack to overcome host resistance. An aggregation is a collection of people who gather in one place, whether of one gender or both. Aggregation pheromones are one of the most environmentally specific pest control strategies available. At shallow doses, they are harmless and effective.

To sum up, Pheromones can boost or control mood, relax, reduce anxiety, and alleviate sadness.

They’re also proven to be incredibly effective in luring insects and control the population by mating disruption.

At ChemHub, we are not entomologists. We focus on chemistry and we only make a few intermediates and semio-chemicals for pheromone industries where entomologists formulate them in traps or spray to disrupt insect mating behavior to minimize or even eradicate particular insect species. The benefits are:

  • Pheromones are non-toxic.
  • Pheromones are environment friendly.
  • Only small amount of pheromones are required.
  • They are alternative solution to pesticide use.
  • Pesticides are harmful and even carcinogenic.
  • Large amount of pesticides are required to control insects.
  • Pesticides destroy the soil quality.
  • Pesticides are also expensive as they are required in large quantities whereas pheromones are extremely cost effective.

Some examples of insect pheromones:

1. Grand lure:
It is basically combination of four chemicals as described below-

It is used control population of specific Insect “Boll Weevil Beetle (Anthonomus grandis)” This pest is from Coleoptera Curculionidea family of insects affecting mainly Cotton crop.

2. Now lure:
It is mainly one single pheromone molecules

With this molecule, sometimes following two ingredients are also used in small quantities

This Pheromone targets specific pest Navel orange worm (NOW) Amyelois transitella which belongs to Lepidotera Pyrralidea family of Insects and It destroys variety of Fruits (figs Pomegranates), Nuts (Almonds, Walnuts, Pistachio) & Citrus fruits like Orange.


Like these pheromones there are several more pheromones that we are capable of production. Few of them are listed below:

  • Gossyplure
  • Codlure
  • Cuelure
  • Disparlure
  • And, many more.

Vanillin based products

There are some products can be made starting from Vanillin. First, let us understand what is Vanillin?

Vanillin is a quite prolific molecule. It is phenolic aldehyde containing two more functional groups, ether and hydroxyl groups.

It can be natural and is generally extracted from Vanilla bean. The natural vanillin is generally called Vanilla and contains the ethoxy analog as well and has very strong note. But, natural vanillin is quite expensive, nearly >15 times than synthetic analog. And it is generally used as flavoring agent in food.

Synthetic Vanillin is now more used to for F&F application and also can used to make other other derivatives for F&F application and also in pharmaceuticals.

There are two types of Vanillin:

Plain Vanillin having methoxy group ((−O−CH3))

CAS No: 121-33-5

Scheme for making Vanillin: Chemical synthesis of Vanillin is a two-step process, in which guaiacol (1) reacts with glyoxylic acid by electrophilic aromatic substitution. The intermediate formed, vanillylmandelic acid (2) is then converted to 4-Hydroxy-3-methoxyphenylglyoxylic acid (3) and finally followed through Vanillin (4) by oxidative decarboxylation.

Ethyl Vanillin having ethoxy group (−O−CH2CH3)

CAS No: 121-32-4

Scheme for making Ethylvanillin: Ethylvanillin is prepared from catechol, beginning with ethylation to give guaethol (1). This ether condenses with glyoxylic acid to give the corresponding mandelic acid derivative (2), which by oxidation (3) and decarboxylation, gives ethylvanillin (4)

Ethyl Vanillin has a stronger note and is more expensive than plain Vanillin.

In this blog, Plain synthetic vanillin will be described. There are a few global producers for Synthetic Vanillin. The first commercial synthesis of vanillin began with natural compound Eugenol, 4-allyl-2-methoxyphenol. Today, artificial vanillin is made either from Guaiacol. The scheme is given below:

Not too long ago, biosynthetic Vanillin was developed, but it became very expensive and is not feasible to make other derivatives economically. The best cost, competitive Vanillin is made from Petrochemical waste Lignin or Guaiacol.

Vanillin has been used as a chemical intermediate in the production of pharmaceuticals, cosmetics, and fine chemicals. Most of vanillin production was used in the synthesis of specialty chemicals. In this blog, four different types of specialty products are described having application in F&F industry.

A general flow chart of four different products can be made from Vanillin that are of importance in Flavor & Fragrance industry

At ChemHub, we have developed the process to make two key intermediates starting from Vanillin:

Vanillyl alcohol (CAS No: 498-00-0) and Vanillyl amine (CAS No: 1196-92-5).

These two key intermediates are used to make final products. Schemes are shown below. The last scheme is the preparation of Vanillin Isobutyrate directly from Vanillin.

  1. Scheme for making Nonivamide:
  2. Scheme for making Capsaicin:
  3. Scheme for making sweet Capsaicin (Capsiate):
  4. Scheme for making Vanillin IsoButyrate (VIB):

Nonivamide:

Vanillin Nonamide is also known as Nonivamide. Nonivamide can also be called pelargonic acid vanillylamide or PAVA.

CAS Number: 2444-46-4

It is in capsaicinoid category. It is manufactured synthetically from Vanillylamine and pelargonic quite cheaper than capsaicin.

Nonivamide is used to add pungency in seasonings and spice blends. It is used in the bakery industry to induce a hot sensation.

and is also used in the pharmaceutical industry as a cheaper alternative to capsaicin.

It can also deter animals, such as deer and squirrel from consuming seeds and crops. It is used in pepper spray irritant for self-defense purpose and can be used in dispersing peaceful demonstration or riot control. It can also be used as lethal in the chemical warfare.

Capsaicin:

CAS Number: 404-86-4

Capsaicin (8-methyl-N-vanillyl-6-nonenamide) is an active component of chili peppers, which can be synthesized as well. It is a chemical irritant for mammals, including humans, and produces a sensation of burning in any tissue with which it comes into contact. Capsaicin and several related are called capsaicinoids having use as deterrents against certain mammals. Pure capsaicin is a hydrophobic, colorless, highly pungent, crystalline solid compound. it is also commonly used in food products to provide added spice and heat. In high concentrations, capsaicin will also cause a burning effect on other sensitive areas, such as skin or eyes. The degree of heat found within a food is often measured on the Scoville scale.

There has long been a demand for capsaicin-spiced products such as Tabasco sauce and Mexican salsa. It is reported to experience pleasurable and even euphoric effects from capsaicin via endorphins release. It also has application for relief of minor aches and pains of muscles and joints associated with arthritis, backache, and sprains,

Capsaicin is being used to reduce the symptoms of peripheral neuropathy, providing pain relief from, HIV-neuropathy, and diabetic neuropathy., Capsaicin is shown to decrease LDL cholesterol levels.

There are six natural capsaicinoids shown below.  Only, Vanillylamide or Nonivamide  (PAVA) and Capsaicin are produced synthetically for most applications

Sweet Capsaicin (Capsiate):

Major capsinoids in nature:


Capsiate ( 4-hydroxy-3-methoxybenzyl (E)-8-methyl-6-nonenoate),                  (CAS No. 205687-01-0)

Dihydrocapsiate (4-hydroxy-3-methoxybenzyl 8-methylnonanoate),                   (CAS No. 205687-03-2)

Nordihydrocapsiate (4-hydroxy-3-methoxybenzyl 7-methyloctanoate),               (CAS No. 220012-53-3)

Capsinoids category include capsiate, dihydrocapsiate, and nordihydrocapsiate, and naturally present in chilli. Even though, structurally similar to Capsaicin, the biggest difference is in Scoville Heat unit (SHU) where the Capsinoids have an estimated 1/1000 that of capsaicin. This is the main reason, the Capsiate is dubbed as “ Sweet Capsaicin”. Many health effects have been reported through scientific study, including anticancer, anti-inflammatory, and analgesic activities, and weight management.

Structural differences between Capsaicin and Capsinoid family of compounds are illustrated below. Capsinoids have an ester bond in their structures, whereas Capsaicin has characteristic amide bond.

Capsaicin vs. Capsinoids?  Which one to chose


Both are shown have same effect except the taste and SHU. The real difference is Capsaicin is more effective to deter animals, where larger amount of Capsiate can be absorbed in the body without burning effect. There are many ongoing investigation for comparison and other benefits.

Vanillin IsoButyrate (VIB):

CAS No: 20665-85-4

LEAF ALCOHOL

Cis-3-Hexenol; (z)-3-Hexen-1-ol

CAS No. 928-96-1

FEMA: 2563

cis-3-Hexen-1-ol, abbreviated as (Z)-3-hexen-1-ol is known as leaf alcohol. Leaf Alcohol is a very important aroma ingredient and is one of the most popular fragrance Ingredient in F&F industry. It has powerful green note resembling fresh Green Grass. In small amounts it gives top-notes of floral fragrance like Lilac. In Flavor formulation, it adds sweet green note to all fruit flavors like Paech Apple & Pear. It is a colorless oily liquid with an intense grassy-green odor of freshly cut green grass. Leaf alcohol also has been recognized as a semiochemical.

cis-3-Hexen-1-ol is an alcohol and its esters are also important flavor and fragrance ingredients.

Also, the leaf aldehyde, which is cis-3-Hexenal has stronger smell but is unstable.

It is traditionally manufactured from Sorbic alcohol by using Chromium catalyst for hydrogenation. Hexavalent Chromium is now classified as highly toxic, Carcinogenic and environmentally hazardous in nature, hence, this catalyst in now not preferred at all creating a shortage for leaf alcohol worldwide and scrambling for availability while the price has been spiralling upwards.

At ChemHub, we have developed two new processes eliminating use of hazardous Chromium catalyst. These new processes are environment friendly Green Chemistry.

 

Leaf Alcohol can be used to make other perfumery chemicals like

Leaf Acetate (cis-3-hexenyl acetate, CAS No: 3681-71-8)

Leaf Tiglate (cis-3-hexenyl tiglate, CAS No: 67883-79-8)

Leaf Aldehyde (cis-3-hexenyl aldehyde, CAS No: 6789-80-6)

 

We plan to offer all these ingredients, June onwards.

Camphanediol | (+,-)-exo,exo-2,3-Camphanediol

Info: Camphanediol, High purity Camphanediol, Camphanediol in New Jersey, Exo-exo-Camphane diol, Exo,exo-2,3-Camphanediol, (+,-)-exo,exo-2,3-Camphanediol, CAS No: 56614-57-4, Camphanediol as Cosmetic Ingredient, Camphanediol Data

This is cosmetic/functional ingredient category. We are making ultrapure high quality material and is more specifically known as Exo-exo Camphanediol. Other manufacturers are doing more exo-endo derivative which is lower quality.

  • CAS Number: 56614-57-4
  • Molecular Formula: C10H18O2
  • Mol. Wt.: 170.25
  • Mp: 250-252 0C
  • Assay: >96% chemical purity; >97% isomeric purity
  • Synonyms: (1R,2S,3R,4S)-rel-1,7,7-Trimethylbicyclo[2.2.1]heptane-2,3-diol
  • Appearance: White crystalline solid

(+,-)-exo,exo-2,3-Camphanediol is utilized as a conditioning agent, affording a soft texture and feel to hair and skin. It is also known to increase microcirculation, leading to its use in several products in the cosmetics industry. Moreover, it has found application as a component in protective surface coatings.

The most common route to (+,-)-exo,exo-2,3-camphanediol (Isomeric purity: >94%) is via the reduction of camphorquinone with hydride reagents such as LiAlH4 and NaBH4.[i]­­­­,[ii] However, LiAlH4 is a toxic and pyrophoric reducing agent with poor solubility in common ether solvents and requires the use of strictly anhydrous reaction conditions. On the other hand, the milder NaBH4 provides the diol product in very low yields.[iii] The alternate synthesis via catalytic hydrogenation over Raney Ni necessitates the use of high pressures (~1000 psi of H2) and provides the (+,-)-exo,exo-2,3-camphanediol in poor diastereoselectivities.1

Pheromones, Semiochemicals and Intermediates

The terminology of pheromones came into existence in the 1950s when Peter Karlson and Martin Luscher began conducting research. Pheromones are organically occurring chemicals that trigger behavioral responses in another member of the same species. Nowadays, synthetic pheromones have become a crucial part of the pheromone industry to control insects and is alternative solution to pesticide industry.

Unlike pesticide, pheromones are required in minute amount and replace toxic pesticide which not only destroy the soil quality, but also pesticide residue can stay in the crops which can be toxic and carcinogenic.
