2'-Chloro acetophenone(Cas 2142-68-9) Usage


2'-Chloroacetophenone, also known as chloroacetophenone or phenacyl chloride, is a white crystalline solid that is denser than water and insoluble in water, causing it to sink. It has a floral odor and is a potent eye, throat, and skin irritant. Acute inhalation exposure can cause burning of the eyes, lacrimation, blurred vision, corneal damage, and irritation and burning of the nose and throat.


Historically, 2'-Chloroacetophenone has been utilized as a riot control agent, designated as CN. It has been used in tear gas, chemical Mace, and riot control agents. Additionally, it is known to produce toxic and corrosive fumes, including hydrogen chloride. Beyond its use in riot control, 2'-Chloroacetophenone (CAS# 2142-68-9) finds utility in organic synthesis, serving as a valuable building block in various reactions. It contributes to the creation of more complex compounds through its role as a key component in certain organic synthesis processes.

Microbial degradation of chlorinated acetophenones

J Havel, W Reineke

, Applied and environmental microbiology, 1993

A defined mixed culture, consisting of an Arthrobacter sp. and a Micrococcus sp. and able to grow with 4-chloroacetophenone as a sole source of carbon and energy, was isolated. 4-Chlorophenyl acetate, 4-chlorophenol, and 4-chlorocatechol were identified as metabolites through comparison of retention times and UV spectra with those of standard substances.
