  • Applications

    Sodium 2-anthraquinonesulfonate is a water-soluble sulfonated anthraquinone derivative used mainly as a dye intermediate and colorant in industrial dye chemistry. It serves as a building block for anthraquinone-based dyes and can be applied directly as a soluble dye or as a component in aqueous dyeing and printing ink formulations for coatings, textiles, and paper. In coatings, inks and related formulations, it provides a hydrophilic colorant source and may function as a dispersant or colorant feedstock in pigment formulations. As an industrial chemical intermediate, it is commonly evaluated for use in the synthesis of dyes and related pigments used in manufacturing. Its use is subject to local regulations and formulation limits.
