DESCRIPTION
General description
Chloroacetic acid (CAA, monochloroacetic acid, MCAA) is a halogenated aliphatic carboxylic acid generally used as herbicide and preservative. Its mutagenic effects have been studied in Rattus norvegicus.[1] The rate of degradation of MCA by photocatalysis using TiO2 at pH3 is reported to be enhanced under the influence of ozone.[2] CAA is an irritant that hydrolyzes proteins resulting in degradation of the cells. This property has been applied in treating plantar warts.[3]
Application
Chloroacetic acid may be used to synthesize the following:
Thiocarbamoylthioacetic acid derivatives.[4]
4-Thiazolone derivatives.[5]
Triazinothiazolone derivatives.[6]
Water soluble carboxymethyl chitosan.[7]
