Description
CATO manufactures Elobixibat Impurity 33 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.
Elobixibat Impurity 33 (CAS CATO-C4X-283833) is a certified pharmaceutical impurity reference standard with the molecular formula C23H30BrNO2S and a molecular weight of 464.46 g/mol.
The molecular framework of Elobixibat Impurity 33 (C23H30BrNO2S) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
