Used as an intermediate in the synthesis of pharmaceuticals and fine chemicals, particularly in the development of active pharmaceutical ingredients (APIs) where bromine functionality allows for further coupling reactions via cross-coupling methodologies such as Suzuki or Heck reactions. The presence of both ester and carboxylic acid groups enables selective derivatization, making it valuable in constructing complex organic molecules. Commonly employed in research settings for the preparation of substituted aromatic compounds with potential biological activity.
