Used as an intermediate in the synthesis of pharmaceuticals and agrochemicals. It serves in the preparation of active ingredients requiring brominated aromatic scaffolds, particularly in the development of nonsteroidal anti-inflammatory drugs (NSAIDs) and other bioactive molecules. The carboxylic acid group allows for coupling reactions, while the bromine atom enables further functionalization via cross-coupling reactions such as Suzuki or Heck reactions. Also employed in the production of dyes and specialty polymers where specific substitution patterns are required for desired electronic or steric properties.
