Used primarily in hair dye formulations, it acts as a key intermediate in the production of oxidative hair colorants. It reacts with couplers in the presence of an oxidizing agent to create a wide range of shades, providing long-lasting and vibrant color. Additionally, it is employed in the synthesis of certain dyes and pigments for textiles, offering excellent color fastness and durability. In research, it serves as a building block for developing new organic compounds with potential applications in materials science and pharmaceuticals.
