Chemical Structure
Description
Based on its molecular formula C26H38NO7SNa, Ursodeoxycholic acid impurity 54 contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 531.64 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
As a process- or degradation-related impurity, Ursodeoxycholic acid impurity 54 (CAS 57011-24-2, C26H38NO7SNa) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.
This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.
CATO manufactures Ursodeoxycholic acid impurity 54 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
