Used as an intermediate in the synthesis of pharmaceuticals and fine chemicals, particularly in the development of nonsteroidal anti-inflammatory drugs (NSAIDs). Its functional groups enable derivatization for creating active pharmaceutical ingredients. Also employed in organic synthesis to build complex aromatic structures due to its amine and carboxylic acid moieties, which allow for peptide coupling and esterification reactions. Additionally, it serves as a building block in the preparation of dyes and UV absorbers in specialty polymers.
