Used as an intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of brominated aromatic compounds with biological activity. It serves in the preparation of active ingredients in some antimicrobial and antifungal agents due to the presence of bromine and functional groups that enhance reactivity. Also employed in research for derivatization of natural products and in the design of specialty chemicals where halogenated benzoic acid structures are required. Its hydroxyl and carboxylic acid groups allow for coupling reactions, making it useful in building complex molecules in medicinal chemistry.
