Primarily used in the hair dye industry, it serves as a key intermediate in the synthesis of oxidative hair colorants. It helps produce long-lasting, vibrant shades by reacting with couplers and developers during the dyeing process. Additionally, it is employed in the production of certain pharmaceuticals, particularly in the synthesis of compounds with antioxidant or anti-inflammatory properties. Its role in organic synthesis also extends to creating dyes for textiles and other materials, offering durability and color stability.
