Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of nonsteroidal anti-inflammatory drugs (NSAIDs). It serves as a building block for active pharmaceutical ingredients due to its aromatic amine and carboxylic acid functional groups, which allow for easy modification and coupling reactions. Also employed in the preparation of dyes and pigments, where its structure contributes to color stability and solubility properties. Additionally, it finds use in research laboratories for the design of novel organic compounds and in the creation of custom derivatives for biological screening.
