Mpicoline

Mpicoline is the common name for 3-methylpyridine, one of the three monomethylated derivatives of pyridine. It is the methylpyridine isomer in which the methyl group is attached to the third position of the pyridine ring (the meta position). Like other picolines, mpicoline is part of a family of heterocyclic compounds that are widely used as intermediates in organic synthesis.

In industry and research, mpicoline is typically produced as part of processes that generate methylpyridine isomers or are used to prepare pyridine-derived building blocks. It can also be obtained from related heterocyclic precursors and is often isolated from mixtures that contain 2- and 4-picoline. Mpicoline serves as a chemical intermediate in the manufacture of pharmaceuticals, agrochemicals, dyes, and specialty chemicals, and may be employed as a solvent or reagent in certain synthetic routes.

Chemically, mpicoline shares properties with other pyridine derivatives, including a distincitve pyridine-like odor and typical heteroaromatic chemistry. It is a liquid at ambient conditions and is handled under standard laboratory or industrial safety practices for volatile, irritant, and potentially flammable organic compounds.

Safety and handling considerations are similar to those for related pyridine compounds: avoid inhalation and skin or eye contact, use in well-ventilated areas, and store away from oxidizers. For detailed hazard, handling, and regulatory information, consult material safety data sheets and local guidelines.
