Products Description

What is Dye intermediate Anthraquinone C14H8O2 CAS 84-65-1?

Anthraquinone (CAS 84-65-1), also known as 9,10-anthraquinone, is an industrially significant organic compound composed of three benzene rings arranged linearly with a central quinone moiety. With the molecular formula C₁₄H₈O₂ and molar mass 208.21 g/mol, it appears as light yellow to orange-red needle-shaped crystals at room temperature, exhibiting typical quinone properties.
The Anthraquinone has a melting point of 286°C, boiling point of 379.8°C, and density of 1.438 g/cm³ at 20°C. In concentrated sulfuric acid, it forms a characteristic yellow solution.

Uses

In the dye industry, anthraquinone serves as a key raw material for synthesizing anthraquinone-based dyes, accounting for over 25% of global dye production. 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, finding use in traditional Chinese medicines like compound aloe vera capsules and Mahuang Runchang Wan (Hemp Seed Intestine-Soothing Pills).

Safety Information

Anthraquinone is irritating to the skin and eyes, and long-term contact may cause dermatitis. Its acute toxicity is low (rat oral LD₅₀ > 5000 mg/kg), but the following risks should be noted:
Environmental hazards: It is chronically toxic to aquatic organisms, and the EU lists it as a "hazardous to the aquatic environment" substance (H411).
Regulatory restrictions: The US FDA stipulates that its migration amount in food contact materials shall not exceed 0.05 mg/kg; the EU REACH regulation lists it as a substance requiring authorization (Annex XIV), restricting its use in specific areas.
