Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Vericiguat Impurity 76.
Vericiguat Impurity 76 (CAS CATO-C4X-289676) is a certified pharmaceutical impurity reference standard with the molecular formula C20H17IN3Br and a molecular weight of 506.18 g/mol.
Based on its molecular formula C20H17IN3Br, Vericiguat Impurity 76 contains a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine/iodine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 506.18 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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), Vericiguat Impurity 76 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.
