Pyridine

Pyridine (CAS 110-86-1), also known by the abbreviation Py, is a foundational heterocyclic base used across pharmaceutical synthesis, agrochemical manufacturing, and specialty chemical production.

With FEMA 2966 status, it also holds a recognized role as a flavoring agent in food applications. In industrial settings, it functions primarily as a solvent, catalyst, and chemical intermediate.

In pharmaceutical manufacturing, pyridine serves as a reaction solvent and base catalyst in the synthesis of antihistamines, sulfonamides, and vitamins, where its ability to neutralize acids drives reaction efficiency.

Agrochemical producers rely on it as a key intermediate in herbicide and insecticide synthesis, particularly for pyridine-derived active ingredients. It is essential for large-scale crop protection manufacturing.

In food and flavor formulation, it contributes characteristic roasted and meaty notes to flavor systems at controlled concentrations under FEMA guidelines. This makes it a versatile tool for flavor chemists.

Home care and industrial cleaning product formulators use pyridine-based derivatives as biocidal actives in disinfectant and preservation systems. These applications ensure high standards of hygiene and safety.

Pyridine is supplied as a clear liquid in drums, IBCs, and bulk tanker quantities. Standard commercial grades include technical grade and pharmaceutical-grade meeting USP and BP specifications.

Buyers sourcing for regulated applications should confirm grade compliance with supplier documentation prior to procurement. Proper handling and storage are required to maintain the integrity of the chemical product.
