2methylpyridine

2-Methylpyridine, also known as 2-picoline, is an aromatic heterocyclic amine with the formula C6H7N. It is one of the three isomeric methylpyridines, along with 3-methylpyridine and 4-methylpyridine, collectively referred to as picolines.

Its structure consists of a pyridine ring bearing a methyl group at the 2-position. The ring nitrogen confers basic character typical of pyridines; the compound can form salts with acids and acts as a ligand in coordination chemistry.

It is a colorless liquid at room temperature with a characteristic, acrid odor. It is flammable and must be stored and handled with appropriate ventilation and away from oxidizers.

2-Methylpyridine is used as an intermediate in organic synthesis, including the preparation of pharmaceuticals, agrochemicals, dyes, and other pyridine derivatives. It serves as a building block for more complex ligands and can be used as a solvent or reagent under certain conditions.

Industrial production is based on methylation or derivatization of pyridine and related feedstocks; it is typically sold as a single isomer or as part of the picoline mixture used in chemical manufacturing.

Handling requires protective equipment; vapors may irritate the eyes and respiratory tract; exposure may have health effects; it is flammable and should be kept away from heat sources.
