1,8-Dihydroxyanthraquinone Usage And Synthesis
Chemical Properties orange-brown or brown powder
Chemical Properties Red-orange to orange crystalline powder or reddish-brown crystalline solid.
Uses Important intermediate in the manufacture of alizarin and indanthrene dyestuffs; forms insoluble Ca, Ba, Pb lakes. Antioxidant in synthetic lubricants; fungicide.
Uses Used as a stimulant laxative, though due to its carcinogenic properties, is not widely prescribed.
Uses cathartic
Definition ChEBI: A dihydroxyanthraquinone that is anthracene-9,10-dione substituted by hydroxy groups at positions 1 and 8.
Brand name Dorbane (3M Pharmaceuticals); Istizin (Sterling Winthrop);Doss;Normax;Regulex-d.
World Health Organization (WHO) Dantron, an anthroquinone derivative, has been available for over twenty years and is widely used as a laxative. The results of two chronic toxicity studies in rodents, published in 1985 and 1986, have shown that administration of high doses is associated with the development of intestinal and liver tumours.
General Description Orange crystalline powder. Almost odorless and tasteless.
Air & Water Reactions Insoluble in water.
