Used as an intermediate in the production of vat dyes, particularly for cotton and other cellulosic fibers. It contributes to the formation of anthraquinone-based dyes that offer excellent light and wash fastness. Also employed in the synthesis of disperse dyes for polyester and acetate fabrics. Plays a role in the manufacture of certain pigments and fluorescent brightening agents. Additionally, it finds use in research and development of organic semiconductors and electroactive materials due to its conjugated structure and electron-accepting properties.
