Description
2,3-Difluorobenzoic acid CAS 4519-39-5 is a difluorinated aromatic carboxylic acid with two fluorine atoms substituted at the 2 and 3 positions of the benzene ring. This fluorinated fine chemical intermediate owns stable molecular structure, good thermal stability and slight solubility in water, while showing excellent solubility in common organic solvents including ethanol, methanol, ethyl acetate and DMF. The dual fluorine substitution structure improves the lipophilicity and chemical reactivity of the compound, making 2,3-Difluorobenzoic acid CAS 4519-39-5 a vital synthetic building block widely used in pharmaceutical intermediate manufacturing, agrochemical synthesis, liquid crystal material production and laboratory organic synthesis.
