Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of nonsteroidal anti-inflammatory drugs (NSAIDs) and other bioactive molecules. Its functional groups allow for further chemical modifications, making it valuable in medicinal chemistry for constructing complex aromatic compounds. Also employed in the preparation of dyes and agrochemicals due to its halogenated aromatic structure. Its amino and carboxylic acid groups facilitate coupling reactions in peptide-like synthesis and heterocycle formation.
