2-methylpyridine

2-Methylpyridine (CAS 109-06-8), commercially known as alpha-picoline, is a nitrogen-containing heterocyclic compound used as a key building block in pharmaceutical synthesis, agrochemical production, and specialty chemical manufacturing. It functions primarily as a chemical intermediate, enabling the construction of more complex active molecules across multiple regulated industries. In pharmaceutical manufacturing, alpha-picoline serves as a precursor to vinylpyridine derivatives.

It is essential for the production of antihistamines and vitamins including B6 and melatonin-related compounds. Agrochemical producers use it to synthesize herbicides and insecticides, particularly chloropyrifos-related intermediates. In flavor and fragrance applications, 2-picoline contributes to the synthesis of specific aroma compounds where its reactivity at the methyl group is commercially exploited. It also functions as a catalyst or co-solvent.

The material is utilized in select organic synthesis processes, including resin and polymer production. 2-Methylpyridine is supplied as a liquid in standard industrial drum and IBC quantities, with bulk tanker options available. Technical grade is the predominant commercial specification, with purity levels typically at 99% or higher confirmed by GC analysis. Pharmaceutical-grade material meeting relevant compendial standards is available for regulated synthesis.

Select manufacturers provide material that adheres to USP or BP standards for specific applications. This ensures high-quality performance across diverse industrial sectors and chemical manufacturing processes.
