Description
Elobixibat Impurity 34 (CAS CATO-C4X-283834) is a certified pharmaceutical impurity reference standard with the molecular formula C25H32BrNO5S and a molecular weight of 538.49 g/mol.
The molecular framework of Elobixibat Impurity 34 (C25H32BrNO5S) is characterized by a flavonoid 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 the protonation state of its nitrogen-containing groups, 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.
As a certified reference material (CRM), Elobixibat Impurity 34 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
