Here is a brief summary what ChemHub can do. 

 

This is just a list of a few items and is more relevant to pheromone companies. Any new projects or new chemistry, can be explored and ChemHub will give some feedback. This is a good starting point to understand our capabilities and explore opportunities.

 

As a rule of thumb, ChemHub requires about 3-4 months to complete the production schedule of general items.
