Used as an intermediate in the synthesis of dyes and pigments, particularly in the production of azo dyes for textiles and inks. Also employed in the development of pharmaceuticals, including certain analgesics and antipyretics, due to its amine functionality. Its hydrochloride salt form enhances solubility and stability in aqueous reaction systems, making it suitable for use in controlled organic syntheses. Additionally, it finds application in the preparation of specialty polymers and photochemicals.
