Heterocyclic compounds represent the largest and most varied class of organic compounds.

For the heterocycles of the most common elements of Oxygen, Nitrogen and Sulfur, the possible permutations for any given ring structure are incredibly numerous. They are important in many biological systems and processes, as such it is not surprising that they find wide application in pharmaceutical, agrochemical, aroma, food and beverage industries.

Having a long tradition in the chemistries of organo-Sulfur, Oxygen and Nitrogen, Robinson Brothers has a wealth of experience in the manufacture and application of many heterocyclic chemicals.
