Used as an intermediate in the synthesis of vat dyes, particularly for producing blue and green shades in cotton, wool, and other textile fibers. It contributes to the development of dyes with excellent lightfastness and wash resistance. Also employed in the production of functional dyes for specialty applications, including electrochromic materials and organic semiconductors due to its stable quinone structure and electron-transfer properties. Its derivatives are explored in optoelectronic devices and as colorants in high-performance pigments.
