Application

Trichloroacetic acid (TCA) can be used as a catalyst to synthesize:
  • β-enaminones via condensation reaction of 1,3-dicarbonyl compounds and amines.
  • 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.
  • Tetrahydrobenzo[a]xanthen-11-ones by three-component reaction of aldehydes, 2-naphthol and dimedone.

Traditionally used to precipitate protein. Has been used to determine protein concentration by quantitative precipitation. Used as decalcifier and fixative in microscopy.
