Vericiguat Impurity 43 CAS CATO-C4X-289643

Description

The occurrence of Vericiguat Impurity 43 is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Vericiguat Impurity 43 (CAS CATO-C4X-289643), a pharmacopoeial impurity reference standard (molecular formula C14H8F2N4, MW 270.24 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C14H8F2N4, Vericiguat Impurity 43 contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 270.24 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.

CATO manufactures Vericiguat Impurity 43 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
