Used as an intermediate in the synthesis of dyes and pigments, particularly for azo dyes which are widely applied in the textile and printing industries. It also serves in the preparation of pharmaceuticals, including anti-inflammatory and analgesic agents, due to its structural compatibility with bioactive molecules. Additionally, it finds use in the development of agrochemicals such as herbicides and plant growth regulators. Its amino and carboxylic functional groups allow for easy modification in organic synthesis, making it valuable in research laboratories for building more complex aromatic compounds.
