bilirubin, bilirubin powder, pharm grade bilirubin cas. 635-65-4
CAS number: 635-65-4
Molecular formula: C33H36N4O6
Molecular weight: 584.66
Appearance: red or brownish red powder
Bilirubin powder is Red or brownish red powder, insoluble in water, soluble in organic solvents such as benzene, chloroform and carbon disulfide, slightly soluble in ethanol and ether, bilirubin can also be dissolved in a mixture of hot ethanol and chloroform, bilirubin The sodium salt is easily soluble in water, but the calcium, magnesium and barium salts are insoluble in water. Bilirubin is a pale orange or dark reddish brown monoclinic crystal. The dry solid is relatively stable, and the chloroform solution is also stable in the dark. It is unstable in alkali solution (such as 0.1mmol/L sodium hydroxide) or trivalent iron ion, and is quickly oxidized to biliverdin. Bilirubin can bind to glycine, alanine or histidine. Adding serum protein, vitamins or EDTA stabilizes bilirubin.

A major component of heme breakdown; a major pigment in bile; a function of an antioxidant and an effective hydrogen peroxide-based scavenger to protect cell membrane lipids from the oxidation of these reactive groups. Bilirubin has a variety of pharmacological effects and is the main raw material for the manufacture of artificial bezoar. Pharmacological experiments have shown that it has a good inhibitory effect on W256 tumors. The inactivation rate and inhibition index of Japanese encephalitis virus are 1 to 1.5 times higher than deoxycholic acid and bile acid; it is also an effective liver disease. The therapeutic drug has the function of proliferating new cells without destroying the liver tissue, and can treat diseases such as serum hepatitis and cirrhosis, and in addition, bilirubin has antipyretic and antihypertensive effects. Promote red blood cell regeneration and other effects.
Application: API ingredient of artificial bezoar.
