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.
Vericiguat Impurity 41 (CAS CATO-C4X-289641) is a certified pharmaceutical impurity reference standard with the molecular formula C14H8F2N4 and a molecular weight of 270.24 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine substitution, Vericiguat Impurity 41 is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 270.24 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
As a certified reference material (CRM), Vericiguat Impurity 41 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.
