Uses

In the dye industry, anthraquinone serves as the core raw material for synthesizing anthraquinone-based dyes, accounting for over 25% of global dye production. Notable examples include Vat Blue RSN (C.I. Vat Blue 4) for cotton and linen dyeing, Acid Blue 80 (C.I. Acid Blue 80) for wool and silk, and Disperse Blue 56 (C.I. Disperse Blue 56) for polyester fibers.

Within the medical field, anthraquinone derivatives such as sennoside A and emodin act as laxatives by stimulating intestinal peristalsis, though prolonged use may lead to colon melanosis. Compounds like mitoxantrone inhibit topoisomerase II and are used in treating breast cancer and acute leukemia.

In the papermaking industry, it functions as a pulping additive to enhance wood pulp yield and reduce energy consumption. For instance, in kraft pulping processes, it shortens cooking time by 15–20% through promoting lignin degradation.
