Used as an intermediate in the synthesis of vat dyes, particularly for producing blue and green shades in cotton and other cellulosic fibers. It contributes to dye stability and color fastness, making it valuable in textile dyeing. Also employed in the production of specialty pigments for inks and coatings where strong, lightfast colors are required. Its structure allows for modification to achieve a range of hue intensities in high-performance dye applications.
