Descripción

Application

Tradicionalmente usado para precipitar proteínas. Se ha utilizado para determinar la concentración de proteína por gravimetría. Usado como descalcificador y fijador en microscopía.

Trichloroacetic acid (TCA) can be used as a catalyst to synthesize:

• β-enaminones via condensation reaction of 1,3-dicarbonyl compounds and amines.[1]
• 6-amino-3-methyl-1,4-diphenyl-1,4-dihydropyrano[2,3-c]pyrazole-5-carbonitrile derivatives via four-component condensation reaction of ethyl acetoacetate, phenylhydrazine, malononitrile, and aromatic aldehydes.[2]
• Tetrahydrobenzo[a]xanthen-11-ones by three-component reaction of aldehydes, 2-naphthol and dimedone.[3]
