Sodium salt of taurocholic acid, a conjugate of 3ฮฑ-hydroxy-5ฮฒ-cholan-24-oic acid and taurine, featuring a sulfate ester at C24 and a carboxylate group complexed with sodium. This compound arises as a synthetic byproduct during parent drug formulation, differing by ionic substitution at the terminal carboxylic acid. Serves as an HPLC reference standard for quantifying impurity profiles in taurocholic acid-based pharmaceuticals.
