Glycochenodeoxycholic acid sodium salt is a conjugated bile acid derivative featuring a 3ฮฑ,7ฮฑ-dihydroxylated steroid nucleus with a glycine moiety linked via an amide bond to the side-chain carboxylate group. This zwitterionic structure, characterized by a sodium counterion, arises from the amidation of chenodeoxycholic acid with glycine, introducing an additional amino functional group. It serves as a critical impurity in the synthesis of chenodeoxycholic acid-based APIs, originating from incomplete conjugation reactions. This compound functions as an HPLC reference standard for quantifying process-related impurities in bile acid pharmaceuticals.
