Used as an intermediate in the synthesis of azo dyes and pigments, particularly for producing high-fastness colorants used in textiles, inks, and coatings. It also serves in the preparation of certain pharmaceuticals and agrochemicals due to its aromatic amine functionality. Its chloro and amine groups allow for selective reactions in multi-step organic syntheses. Additionally, it is employed in the development of epoxy curing agents, enhancing thermal and chemical resistance in polymer systems.
