3. Comprehensive Product Applications
3.1 Dyestuff Industry (Main Application)
Core intermediate for manufacturing anthraquinone series vat dyes, disperse dyes and acid dyes. It undergoes sulfonation, amination, halogenation to produce blue, red and green anthraquinone dyes with bright color, excellent light fastness and washing fastness for textile printing and dyeing.
3.2 Paper Pulp Bleaching Industry
Photosensitizer for hydrogen peroxide bleaching of wood pulp and straw pulp. Under ultraviolet irradiation, it improves bleaching efficiency, reduces bleaching temperature and dosage of hydrogen peroxide, protects fiber strength.
3.3 Fine Chemical & Photoinitiator
Raw material for synthesizing organic photoinitiators, optical brighteners and organic pigments; used in coating, ink and photoresist formulations.
3.4 Organic Synthetic Research Reagents
Standard fused ring aromatic reagent for organic chemistry laboratories, used for research on anthracene derivative synthesis and photochemical reaction mechanism.
