Properties and Applications: commonly known as 1,2-Dihydroxyanthracene-9,10-dione , calcium, aluminum mordanting for red to blue light red, chromium for dark blue light red, iron as dark purplish red. Claybank powder. Slightly soluble in water, but soluble in Methanol, Acetone Etanol, boiling, alkali and Cellosolve, slightly soluble in benzene, Carbon tetrachloride, insoluble in cold Etanol, Stout solvent, soluble in alkali liquor for royal purple. In concentrated sulfuric acid for yellow red, red yellow after diluted produce precipitation; In the Sodium hydroxide to purple. Used for wool fabric dyeing and used as organic pigment.
