Specifications | MSDS | Literature and Reviews


2,6-Dihydroxyanthraquinone (CAS number 84-60-6), also known as anthraflavic acid, a plant metabolite, is a 9,10-anthraquinone derivative with the central ring bearing two carbonyl groups being fused to two fully aromatic six-membered rings. It is an isomer of the alizarin dye with a crystal packing as superimposed molecular sheets. Carbonyl dyes has been well  known to provide a wide range of colors almost covering the entire visible spectrum, in particular, 9,10-anthraquinone derivatives can give rise to a complete range of shades.

2,6-Dihydroxyanthraquinone is a potent inhibitor of the O-deethylations of ethoxycoumarin and ethoxyresorufin, both catalysed primarily by cytochromes P-448. Anthraflavic acid is a potent inhibitor of 2-amino-3-methylimidazo[4,5-f]quinoline (IQ) mutagenicity by virtue of its ability to inhibit both its microsomal and cytosolic activation pathways.

It has also been demonstrated that protons can be reversibly intercalated and deintercalated in crystalline 2,6-dihydroxyanthraquinone (DHAQ) at a potential of −0.21 V in acidic solution with a specific capacity of 110 mAh g-1. The quinone proton battery delivers an equilibrium voltage of 1.1 V, and the capacity retention rate could be as high as 100% after 2600 cycles.
