Description
Pemafibrate Impurity 53 (CAS CATO-C4X-290353) is a certified pharmaceutical impurity reference standard with the molecular formula C9H15F3O5S and a molecular weight of 292.27 g/mol.
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, Pemafibrate Impurity 53 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 292.27 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), Pemafibrate Impurity 53 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.
