Used as an intermediate in the synthesis of dyes and pigments, particularly in the production of azo dyes for textiles, inks, and coatings. It also serves in the development of agrochemicals and pharmaceuticals due to its aromatic amine functionality, which allows for coupling reactions and the formation of complex organic molecules. Its structure supports electron delocalization, making it useful in specialty polymers and optical brighteners. Handling requires caution due to potential toxicity and sensitization risks.
