1,4-Diamino anthraquinone Cas 128-95-0

Core intermediates for Vat Blue and Disperse Blue dyes: Used to synthesize high-end vat, disperse, and solvent dyes in blue and purple shades; suitable for high-temperature dyeing of polyester, cotton, and synthetic fabrics, offering excellent color fastness.
Raw materials for solvent dyes / oil-soluble dyes: Used to produce colorants for plastics, resins, lubricating oils, and paraffin wax; suitable for coloring engineering plastics such as PET, PVC, and nylon, providing transparent, non-migrating color.
Synthetic building blocks for cationic and reactive dyes: Undergo alkylation and sulfonation of the amino group to produce water-soluble Reactive Blue and Cationic Blue dyes, used for printing and dyeing silk and wool.
Intermediates for organic pigments: Used to synthesize high-end anthraquinone-based organic violet and blue pigments for inks, coatings, and artist color pastes; these offer superior weather resistance compared to azo pigments.
