What is Trichloroacetic acid?
Trichloroacetic acid is a monocarboxylic acid that is acetic acid in which all three methyl hydrogens are substituted by chlorine. It has a role as a metabolite, a carcinogenic agent and a mouse metabolite. It is a monocarboxylic acid and an organochlorine compound. It is functionally related to an acetic acid. It is a conjugate acid of a trichloroacetate.
