Used as an intermediate in the synthesis of dyes and pigments, particularly in the production of azo dyes due to its aromatic amine functionality. Also serves as a building block in the preparation of polymers and heterocyclic compounds. Its maleamic acid group allows for further chemical modifications, making it useful in pharmaceutical research for developing bioactive molecules. Additionally, it has been explored in the development of corrosion inhibitors and in coordination chemistry as a ligand for metal ions.
