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.
