1,2-Difluorobenzene has been used as solvent for the electrochemical analysis of transition metal complexes. It is relatively chemically inert, weakly coordinating, and has a dielectric constant high enough to dissolve many electrolytes and metal complex salts. It is used as a weakly coordinating solvent for metal complexes, alternative to the relatively more strongly coordinating solvents acetonitrile, DMSO, and DMF.
It has a role as an anaesthetic.
1,2-Difluorobenzene can be acylated to 3',4'-difluoropropiophenone, which has interesting application in the synthesis of halogenated cathinone/PPA congeners.
DFB is a highly flammable liquid and vapour. Hazardous decomposition products formed under fire conditions include carbon oxides, and hydrogen fluoride. Handle with thick fluorinated rubber gloves.
