General description
Difluoroaceticacid is a monocarboxylic acid and an organofluorine compound. Difluoroaceticacid is easy-to-handle reagent, useful for obtaining difluoromethyl substituents. Difluoroacetic acid can be used asdifluoromethylating reagent for the direct C−H difluoromethylation ofheteroaromatic compounds.
Application
Used in the preparation of 2-difluoromethylbenzimidazoles, -oxazoles and -thiazoles from ortho-substituted anilines mediated by triphenylphoshine.

To facilitate mass transport and column efficiency, solutes must have free access to particle pores to facilitate interactions with the stationary phase. To ensure this feature, particles should be used for HPLC separations which have pores sufficiently large to accommodate

Dichloroacetic acid (DCA), chlorofluoroacetic acid (CFA), and difluoroacetic acid (DFA) are inhibitors of pyruvate dehydrogenase kinase. DCA is used for the clinical management of congenital lactic acidosis. Glutathione transferase zeta (GSTZ1-1) catalyzes the biotransformation of DCA and CFA, and DCA
