Description

General description

Chloroacetic acid (CAA, monochloroacetic acid, MCAA) is a halogenated aliphatic carboxylic acid. Its mutagenic effects have been studied in Rattus norvegicus. The rate of degradation of MCA by photocatalysis using TiO₂ at pH3 is reported to be enhanced under the influence of ozone. CAA is an irritant that hydrolyzes proteins resulting in degradation of the cells. This property has been applied in treating plantar warts.

Application

Chloroacetic acid may be used to synthesize the following:

• Thiocarbamoylthioacetic acid derivatives.
• 4-Thiazolone derivatives.
• Triazinothiazolone derivatives.
• Water soluble carboxymethyl chitosan.
