Used as an intermediate in the synthesis of dyes and pigments, particularly for azo dyes that require substituted aromatic amines for color development. It also serves in the production of pharmaceuticals, where its amino and carboxylic functional groups allow incorporation into active molecules, especially in anti-inflammatory or analgesic compounds. Additionally, it finds use in agrochemicals for the development of certain herbicides and plant growth regulators due to its structural specificity. Its derivatives may also be explored in polymer chemistry as monomers or cross-linking agents.
