 Bilirubin (CAS NO.635-65-4) is used as principal pigment of bile and constituent of many biliary calculi. And also used to be artificial bezoar for the determination of bilirubin in artificial calculus bovis preparation and biochemistry. Bilirubin (CAS NO.635-65-4) has a variety of pharmacological effects, is to create artificial bezoar of the main raw material.

 Bilirubin (CAS NO.635-65-4) is mainly extracted from the bile. Bilirubin is made from fresh cow or pig bile through the bile quicklime role in generating bilirubin calcium, and then hydrochloric acid, chloroform solvent extraction.

 Bilirubin (CAS NO.635-65-4) is also called Hematoidin;bilirubin (ex pig) ; 21H-Biline-8,12-dipropanoic acid,2,17-diethenyl-1,10,19,22,23,24-hexahydro-3,7,13,18-tetramethyl-1,19-dioxo- ; 2,17-Diethenyl-1,10,19,22,23,24-hexahydro-3,7,13,18-tetramethyl-1,19-dioxo-21H-biline-8,12-dipropanoic acid ; 13,18-Tetramethyl-1,19-dioxo- ; 1,10,19,22,23,24-hexahydro-2,7,13,17-tetramethyl-biline-12-dipropionicacid . Bilirubin (CAS NO.635-65-4) is soluble in benzene, chloroform and carbon disulfide and other organic solvents; also soluble in hot ethanol and chloroform mixture; salt soluble in water, but calcium, magnesium and barium salts do not dissolve in water. Bilirubin is created by the activity of biliverdin reductase on biliverdin. Bilirubin, when oxidized, reverts to become biliverdin once again. This cycle, in addition to the demonstration of the potent antioxidant activity of bilirubin, has led to the hypothesis that bilirubin's main physiologic role is as a cellular antioxidant.
