About HS Code 293331
This HS code specifically covers Pyridine and its salts, which are heterocyclic compounds containing an unfused pyridine ring. Pyridine is a fundamental and versatile chemical building block, widely utilized as a solvent, a reagent in organic synthesis, and an intermediate in the production of pharmaceuticals, agrochemicals, vitamins (e.g., niacin), and specialty chemicals. Its unique basicity and aromaticity make it indispensable in various chemical reactions. Major importers and exporters include large chemical companies, pharmaceutical manufacturers, and research institutions globally. Trade typically involves bulk quantities for industrial applications, highlighting its importance as a foundational chemical in numerous manufacturing processes worldwide.
Products Under This Code
Pyridine, Pyridine hydrochloride, Pyridine N-oxide, 2-Aminopyridine, 4-Dimethylaminopyridine (DMAP)
Real World Examples
