Used as an intermediate in the synthesis of pharmaceuticals, particularly in the production of non-steroidal anti-inflammatory drugs (NSAIDs) and other bioactive compounds. It serves as a building block in organic synthesis due to the presence of both amino and carboxylic acid functional groups, allowing for coupling reactions and the formation of amides, esters, and heterocyclic compounds. Also employed in the development of agrochemicals and dyes where substituted aromatic amines are required. Its chloro substituent enables further functionalization through cross-coupling reactions, expanding its utility in medicinal chemistry research.
