Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) where brominated aromatic scaffolds are required. Its functional groups—bromine, carboxylic acid, and hydroxymethyl—allow for selective modifications through cross-coupling reactions, esterifications, or reductions, making it valuable in medicinal chemistry for building complex molecules. Commonly employed in the preparation of enzyme inhibitors and receptor modulators. Also utilized in research settings for the design of novel organic compounds and in the creation of derivatives for structure-activity relationship (SAR) studies.
