Descrizione

Descrizione generale

Chloroacetic acid (CAA, monochloroacetic acid, MCAA) is a halogenated aliphatic carboxylic acid. 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]

Applicazioni

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]
