Pharmaceutical-grade Ursodeoxycholic Acid (UDCA, CAS 128-13-2), 98.5–101.0%, supplied wholesale by Zyntex to licensed producers. Bile acid API for hepatology and gallstone tablets, bovine or plant-based origin. CoA and SDS.
Ursodeoxycholic acid (C24H40O4) is a white or almost white crystalline powder with a bitter taste. It is practically insoluble in water and freely soluble in ethanol. Small amounts occur naturally in human bile, and the name comes from bear bile, where it was first identified.
Traditional production starts from cholic acid obtained from bovine bile. Newer routes use plant sterols and enzymatic steps, which give non-animal UDCA; buyers should check the origin on the documentation, as it matters for TSE/BSE and religious requirements.
Pharmaceutical companies use UDCA in tablets and capsules for cholestatic liver conditions and for dissolving certain gallstones. Related gastroenterology APIs in our range include Mesalazine and Lactulose, and its natural conjugates in bile contain Taurine.
