Taurochenodeoxycholic acid sodium salt is the sodium salt form of taurochenodeoxycholic acid (TCDCA) (CAS: 6009-98-9), with the chemical formula C₂₆H₄₄NO₅SNa and molecular weight 521.69 g/mol. As a stable salt form of conjugated bile acids, it exhibits significantly enhanced water solubility (>500 mg/mL) and is widely used in in vitro diagnostics and pharmaceutical formulations. The United States Pharmacopeia (USP-NF) listed it as a parenteral nutrition additive in 2021, while the European EMA approved it in 2023 for replacement therapy of rare bile acid metabolism disorders (EMA/OD/034/2023).
