Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of nonsteroidal anti-inflammatory drugs (NSAIDs) and other bioactive molecules. Its functional groups—amino, bromo, and carboxylic acid—allow for selective chemical modifications, enabling coupling reactions, ring formations, and derivatizations in multi-step organic syntheses. Commonly employed in the preparation of heterocyclic compounds and as a building block in medicinal chemistry for structure-activity relationship studies. Also finds use in the production of dyes and functional polymers due to its aromatic and reactive nature.
