4-methylpyridine

4-Methylpyridine (CAS 108-89-4) is a pyridine-based heterocyclic building block used across pharmaceutical synthesis, agrochemical manufacturing, and specialty chemical production. It functions primarily as a reactive intermediate and catalyst. In pharmaceuticals, it serves as a key precursor in the synthesis of isonicotinic acid derivatives and active pharmaceutical ingredients targeting cardiovascular and neurological conditions. Agrochemical producers use it to manufacture herbicides.

In coatings and adhesive formulations, it acts as a curing catalyst and crosslinking accelerator for epoxy systems, influencing cure rate and final film performance. It is also known as p-picoline or gamma-picoline. At trace concentrations, it contributes roasted and nutty flavor notes in food applications, with usage governed by FEMA-recognized flavor standards. This versatility makes it essential for various industrial sectors.

The compound is supplied as a liquid at standard commercial purities, typically 98% and 99%+ grades for pharmaceutical and synthesis applications. Technical-grade material is available for industrial catalyst use. Packaging ranges from drums to ISO tank quantities depending on volume requirements. Our supply chain ensures consistent quality meeting USP and FCC standards where applicable for specific high-purity industrial needs.
