2-Chloropyridine is an organohalide with the formula C5H4ClN. It is a colorless liquid that is mainly used to generate fungicides and insecticides in industry. It also serves to generate antihistamines and antiarrythymics for pharmaceutical purposes.

Structure and properties
2-Chloropyridine reacts with nucleophiles to generate pyridine derivatives substituted at the second and fourth carbons on the heterocycle. Therefore, many reactions using 2-chloropyridine generate mixtures of products which require further workup to isolate the desired isomer.
Main reactions and applications
2-chloropyridine is primarily used to generate other pyridine derivatives. Some commercial products include pyrithione, pyripropoxyfen, chlorphenamine, and disopyramide. These reactions rely on chloride’s nature as a good leaving group to facilitate the transfer of a substrate onto the pyridine ring. Pyrithione, the conjugate base of 2-mercaptopyridine-N-oxide, is a fungicide found in some shampoos. It is generated from 2-chloropyridine by reacting the N-oxide of 2-chloropyridine with Na2S in a basic solution, before adding aqueous HCl.Used as an antihistamine, pheniramine may be generated via several different pathways. One synthesis is to hydroformylate functionalized olefins. This reaction proceeds by reacting phenylacetonitrile with 2-chloropyridine in the presence of a base. The resulting intermediate is then alkylated by 2-(dimethylamino)ethyl chloride and the cyano group removed.
