Description
As a certified reference material (CRM), Finerenone Impurity 61 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.
Finerenone Impurity 61 (CAS CATO-C4X-288061) is a certified pharmaceutical impurity reference standard with the molecular formula C26H28N4O4 and a molecular weight of 460.52 g/mol.
Structurally, Finerenone Impurity 61 (C26H28N4O4) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 15.0, corresponding to approximately 15 ring(s) or double-bond equivalent(s). With a molecular weight of 460.52 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.
