Picoline degradation appears to be mediated primarily by bacteria, with the majority of isolates belonging to the Actinobacteria. 3-Methylpyridine degrades more slowly than the other two isomers, likely due to the impact of resonance in the heterocyclic ring.
2-Methylpyridine, or 2-picoline, is the compound described with formula C 6 H 7 N. 2-Picoline is a colorless liquid that has an unpleasant odor similar to pyridine. It is mainly used to make vinylpyridine and the agrichemical nitrapyrin .
3-Methylpyridine or 3-picoline, is an organic compound with formula 3-CH 3 C 5 H 4 N. It is one of three positional isomers of methylpyridine, whose structures vary according to where the methyl group is attached around the pyridine ring. This colorless liquid is a precursor to pyridine derivatives that have applications in the pharmaceutical ...
Picolinic acid is an organic compound with the formula NC 5 H 4 CO 2 H.It is a derivative of pyridine with a carboxylic acid (COOH) substituent at the 2-position. It is an isomer of nicotinic acid and isonicotinic acid, which have the carboxyl side chain at the 3- and 4-positions, respectively.
4-Methylpyridine is the organic compound with the formula CH 3 C 5 H 4 N. It is one of the three isomers of methylpyridine.This pungent liquid is a building block for the synthesis of other heterocyclic compounds.

The conversion is an example of a structurally complex compound efficiently made from simple precursors. Under related conditions, the condensation of acetaldehyde and ammonia delivers 2-picoline. Oxidation of 5-ethyl-2-methylpyridine with nitric acid gives nicotinic acid via the decarboxylation of 2,5-pyridinedicarboxylic acid. [1]
