Used as a red pigment and vat dye in high-performance coatings, plastics, textiles, and inks due to excellent lightfastness, chemical resistance, and thermal stability. Commonly applied in automotive paints, industrial finishes, cotton and polyester dyeing, composite materials, and specialty printing inks where durability and color retention are critical. Also investigated for use in organic semiconductors and photovoltaic devices because of its extended π-conjugated structure and electron-accepting properties. Shows potential in dye-sensitized solar cells and thin-film transistors.
