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—bromine, hydroxyl, and carboxylic acid—allow for selective chemical modifications, enabling coupling reactions, derivatization, and ring transformations. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies due to its aromatic scaffold and ease of substitution. Also utilized in the preparation of agrochemicals and specialty polymers where halogenated aromatic acids enhance stability and reactivity.
