Description
Anthraquinone (CAS 84-65-1, EC 201-549-0, formula C14H8O2) is a polycyclic aromatic ketone traded under names including Hoelite, Morkit, CORBIT, Az-Q, and DAQ-N. It carries no assigned E-code. It serves as a foundational building block in dye and pigment chemistry across industrial manufacturing.
In textile and paper processing, anthraquinone acts as a redox catalyst in kraft pulping, accelerating lignin breakdown by shuttling electrons between cellulose fibres and the cooking liquor. In printing inks and hair dye formulations, its chromophore structure provides stable colour through conjugated carbonyl groups that absorb visible light selectively.
Anthraquinone is supplied as a powder in technical and synthesis grades, compliant with REACH registration requirements for EU market supply. Packaging is typically available in 25 kg bags or fibre drums. Buyers should confirm grade specification and SDS documentation prior to procurement for regulated end-use applications.
