Anthraquinones (also known as anthraquinonoids) are a class of naturally occurring phenolic compounds based on the 9,10-anthraquinone skeleton. They are widely used industrially and occur naturally.
Carmine, a bright-red pigment derived from insects.[6]
Hypericin and fagopyrin are naphthodianthrones, anthraquinone-derivatives.
Applications
In the production of hydrogen peroxide
A large industrial application of anthraquinones is for the production of hydrogen peroxide. 2-Ethyl-9,10-anthraquinone or a related alkyl derivative is used, rather than anthraquinone itself.[7]
Sodium 2-anthraquinonesulfonate (AMS) is a water-soluble anthraquinone derivative that was the first anthraquinone derivative discovered to have a catalytic effect in the alkaline pulping processes.[9]

The 9,10-anthraquinone skeleton occurs in many dyes, such as alizarin.[10] Important derivatives of 9,10-anthraquinone are 1-nitroanthraquinone, anthraquinone-1-sulfonic acid, and the dinitroanthraquinone.[11]

Medicine
Derivatives of 9,10-anthraquinone include drugs such as the anthracenediones and the anthracycline family of chemotherapy drugs. The latter drugs are derived from the bacterium Streptomyces peucetius, discovered in a soil sample near the Adriatic sea. Drugs in the anthraquinone family include the prototypical daunorubicin, doxorubicin, mitoxantrone, losoxantrone, and pixantrone. Most of these drugs, with the notable exception of pixantrone, are extremely cardiotoxic, causing irreversible cardiomyopathy, which can limit their practical usefulness in cancer treatment.[11]
