Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of anti-inflammatory and antimicrobial agents. Its functional groups—bromine, hydroxyl, and ester—allow for selective chemical modifications, making it valuable in constructing complex organic molecules. Commonly employed in cross-coupling reactions such as Suzuki or Heck reactions to form carbon-carbon bonds in drug discovery research. Also utilized in the preparation of heterocyclic compounds due to its reactive aromatic scaffold.
