Difluoroacetic acid is a chemical compound with formula CHF2COOH. It is a dihalogenocarboxylic acid, specifically a structural analog of acetic acid with two of three hydrogen atoms on the alpha carbon replaced with fluorine atoms. In solution, it dissociates to form difluoroacetate ions. Difluoroacetic acid can also be used as direct C-H difluoromethylating reagent.[2]
