Common Name4-Methylpyridine
Description4-Methylpyridine, C6H7N or CH3C5H4N, also known as 4-mepy or 4-picoline, is a member of the class of compounds known as methylpyridines. It is one of the three isomers of methylpyridine. Methylpyridines are organic compounds containing a pyridine ring substituted at one or more positions by a methyl group. 4-Methylpyridine is a very strong base with a green flavor. It is a light-yellow liquid that is soluble in water. 4-Methylpyridine has a can be found in coffee, shrimp, pork, fig leaf and tea leaf, which makes it a potential biomarker for the consumption of these food products ( Ref:DOI ). This pungent liquid is a building block for the synthesis of other heterocyclic compounds. Its conjugate acid, the 4-methylpyridinium ion, has a pKa of 5.98, about 0.7 units above that of pyridine itself. 4-Methylpyridine is both isolated from coal tar and is synthesized industrially. It forms via the reaction of acetaldehyde and ammonia in the presence of an oxide catalyst. The method also makes some 2-methylpyridine. 4-Methylpyridine, while of little intrinsic value,  is a precursor to other commercially significant species, often of medicinal interest. For example, ammoxidation of 4-methylpyridine gives 4-cyanopyridine, the precursor to a variety of other derivatives such as the antituberculosis drug isoniazid ( Ref:DOI ). 4-Methylpyridine is formed during the combustion of cannabis and is therefore a constituent of cannabis smoke ( Ref:DOI ).
