Uses
1,2,5,8-TETRAHYDROXYANTHRAQUINONE is Al salts dark red, cotton mordanted with Cr salts bluish-violet. No longer used as a dye, except occasionally in printing cotton.
Definition
ChEBI: A tetrahydroxyanthraquinone having the four hydroxy groups at the 1-, 2-, 5- and 8-positions.
Preparation
Quinalizarin. 1,2-Dihydroxyanthracene-9,10-dione or 1,4-Dihydroxyanthracene-9,10-dione with great excess fuming sulfuric acid oxidation and hydrolysis.
Biochem/physiol Actions
Quinalizarin is a potent (IC50 = 110 nM), ATP-competitive, and highly selective (IC50 >1μM against CK1 and 72 other kinases) casein Kinase II (CK2) inhibitor.
Properties and Applications
violet (chromium), dark red light purple (aluminum). Soluble in ethanol. In concentrated sulfuric acid for blue purple, dilution after dark red precipitation.
