|  |  | 3,5-Difluorobenzoic acid Usage And Synthesis | 
 | Chemical Properties | off-white needles and chunks |  | Uses | 3,5-Difluorobenzoic Acid can be used as reactant/reagent in Rh(III)-catalyzed regioselective heterocyclization of benzoic acids with acrylates to give phthalides with water as the solvent |  | General Description | 3,5-Difluorobenzoic acid forms dimers that were stabilized by hydrogen bonds between carboxyl groups. The on-line determination of 3,5-difluorobenzoic acid in water was studied using membrane inlet mass spectrometry with in-membrane preconcentration. |
