Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Faropenem Impurity 57.
Faropenem Impurity 57 (CAS CATO-C4X-128957) is a certified pharmaceutical impurity reference standard with the molecular formula C24H27N2O10S2 and a molecular weight of 567.61 g/mol.
Structurally, Faropenem Impurity 57 (C24H27N2O10S2) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 12.5, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 567.61 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), Faropenem Impurity 57 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.
