It is one of three isomeric monochlorinated benzaldehyde. 3-Chlorobenzaldehyde and 4-chlorobenzaldehyde are the other isomers. Whereas benzaldehyde is prone to autoxidation, the 2-chloro derivatives are more air-stable. Synthesis and uses It is produced by hydrolysis of 2-chlorobenzal chloride:10.1002/14356007.a03_463.pub2 Benzaldehyde Ullmann's Encyclopedia of Industrial Chemistry 2011 Brühne Friedrich Wright Elaine 978-3-527-30385-4 ClC6H4CHCl2 + H2O -> ClC6H4CHO + 2 HCl 2-Chlorobenzaldehyde is used in production of CS gas. It reacts with malononitrile to form CS.Synthesis of ortho-chlorobenzalmalononitrile https://patents.google.com/patent/US3963770A 2-Chlorobenzaldehyde is used in the synthesis of: Clopidogrel, Amlodipine, Levamlodipine, Zotepine, Clobenzorex, Tradipitant, Lodaxaprine, Bay-k-9320, SK 609, Sephin 1 & YC 170.
