Used in organic synthesis as an intermediate for pharmaceuticals and fine chemicals. Its structure allows for further functionalization, making it valuable in the development of active pharmaceutical ingredients (APIs). The bromine substituent enables cross-coupling reactions, such as Suzuki or Heck reactions, useful in building complex aromatic systems. The hydroxy and carboxylic acid groups provide sites for esterification or amidation, supporting its role in prodrug design or polymer conjugation. Also employed in the synthesis of analgesic or anti-inflammatory compounds due to the phenyl ring and functional group arrangement.
