Used in the synthesis of hair dye formulations due to its ability to produce long-lasting color through oxidative coupling with other dye intermediates. It is commonly found in permanent and semi-permanent hair color products, where it contributes to shades ranging from brown to black depending on the formulation. Also employed in the development of photographic developers and dyes for textiles, offering good lightfastness and color intensity. Its reactivity makes it suitable for use in the production of specialty chemicals and intermediates in organic synthesis.
