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 heterocyclic compounds due to the presence of both amino and carboxylic acid functional groups, enabling ring formation in drug molecules. Also employed in the preparation of dyes and agrochemicals where substituted aromatic amines are required. Its structural properties make it suitable for coupling reactions in organic synthesis.
