Description and Uses

Danthron, a natural product, was originally extracted from the roots and rhizome of Polygonaceae plant, also called Da Huang in traditional Chinese herbal medicine. Now it is synthesized in many countries, such as Germany, India, Japan, Poland, the United Kingdom, and the United States. Danthron is reasonably anticipated to be a human carcinogen.
Danthron is an anthraquinone that exists at room temperature as a red or orange crystalline powder.It is practically insoluble in water, but soluble in a variety of solvents (acetone, chloroform, diethyl ether, ethanol) and alkaline hydroxide solutions. The stability of danthron is generally good. It is stable under room temperatures and normal pressures.
