Used as an intermediate in the synthesis of hair dye formulations, particularly in permanent and oxidative colorants. It contributes to color development by participating in coupling reactions with other aromatic amines in the presence of an oxidizing agent, typically hydrogen peroxide. The compound helps produce a range of natural-looking brown to black shades. Its structure allows for good color fastness and gray coverage. Also utilized in the preparation of certain photographic developers and dyes for specialty textiles. Due to its reactivity and potential sensitization, it is handled with care in industrial settings.
