2-Chlorobenzaldehyde

Uses2-Chlorobenzaldehyde has been used in generation of small focused library of diversely functionalized dihydropyrimidine derivatives via one-pot three-component Biginelli cyclocondensation of β-ketoesters, aldehydes and thioureas.

Uses2-Chlorobenzaldehyde can be used to make alcohols, acids, and dyes; used in the rubber, tanning, and paper industries; used as an intermediate for optical brighteners, agricultural chemicals, and pharmaceuticals.It can also be used to prepare triphenyl methane and related dyes, organic intermediate.

General Description2-chlorobenzaldehyde is a clear colorless to yellowish liquid. (NTP, 1992)

Preparation2-Chlorobenzaldehyde is produced mainly by chlorination of 2-chlorotoluene to form 2-chlorobenzal chloride, which is then subjected to acid hydrolysis. Metal salts, such as iron(III) chloride, are used as catalysts. The hydrolysis can also be accomplished using formic acid without a catalyst.2-Chlorobenzaldehyde can also be produced by oxidation of 2-chlorobenzyl chloride with N-oxides of tertiary amines or with dilute nitric acid.https://pubchem.ncbi.nlm.nih.gov/compound/2-Chlorobenzaldehyde
