What are Intermediates?

Intermediates are highly purified chemical substances produced during the synthesis of an Active Pharmaceutical Ingredient (API). They serve as essential "building blocks," used in key chemical reactions to gradually construct a complex drug molecule.
High-quality intermediates enable pharmaceutical companies to conduct preclinical and clinical research more swiftly and efficiently, accelerating the time-to-market for new drugs.
