Used as a dye intermediate in the textile industry, particularly for producing anthraquinone-based vat and disperse dyes. It imparts bright blue or greenish-blue shades on polyester and cellulose fibers. Also employed in the synthesis of biologically active compounds due to its redox-active anthraquinone core. Shows potential in analytical chemistry as a chromogenic reagent for metal ion detection. Its hydroxyl and acetamido groups allow for easy structural modification to tune solubility and binding properties.
