Used primarily in the synthesis of azo dyes and pigments due to its aromatic amine structure, which readily undergoes diazotization. It serves as a key intermediate in the production of specialty dyes for textiles, inks, and coatings. Also employed in the manufacture of certain pharmaceuticals and agrochemicals where substituted anilines are required. Its hydrochloride form enhances stability and solubility during chemical processing. Handle with care due to potential toxicity and carcinogenicity associated with aromatic amines.
