2-Chloro-5-Methylpyridine

Description :

Applications
The solution of 2-chloro-5-methylpyridine so obtained may be used directly for further chlorination to form 2-chloro-5-trichloromethylpyridine with, for example, chlorine gas in the presence of a free radical initiator. This chemical intermediate is useful in the synthesis of certain herbicidal compounds.
Description
2-Chloro-5-methylpyridine is a pesticide intermediate. Its synthesis by many methods has been reported.
Preparation
433,273, 2-chloro-5-methylpyridine is obtained by condensing propionaldehyde and an acrylic ester to form a 4-formylpentanoate ester which may then be aminated with a nitrogen source such as an amine or ammonium compound to form 5-methyl-3,4-dihydro-2(1H)-pyridone.
Chemical Properties
2-Chloro-5-methylpyridine is a colorless to pale yellow liquid with a pungent odor, exhibiting high reactivity due to the presence of a chlorine atom and a methyl group on a pyridine ring, important for various chemical reactions and organic synthesis.
Definition
2-Chloro-5-methylpyridine is an organic compound with the chemical formula C6H6ClN, consisting of a pyridine ring substituted with chlorine and a methyl group, often used as an intermediate in pharmaceutical and agrochemical synthesis.
