Starting with over 600 substituted pyridines and extending through a wide array of other N, O, and S ring systems, heterocycles have long been a core area of expertise for Asymchem. Asymchem has considerable experience producing this class of compounds from gram to metric ton scales and offers more than 400 heterocycles in our catalog as further evidence of this expertise.
