Used as an intermediate in the synthesis of anthraquinone dyes and pigments, particularly in the production of vat dyes for cotton and other cellulosic fibers. It contributes to the development of red and orange shades with good light and wash fastness. Also employed in the manufacture of functional organic materials where quinone structures are needed for electron transfer properties. Its hydroxyl and methyl substituents enhance solubility and reactivity in polar solvents, making it suitable for catalytic and photochemical applications.
