Vericiguat Impurity 89 CAS CATO-C4X-289689 chemical structure

Description

Vericiguat Impurity 89 (CAS CATO-C4X-289689) is a certified pharmaceutical impurity reference standard with the molecular formula C14H9FN4 and a molecular weight of 252.25 g/mol.

Based on its molecular formula C14H9FN4, Vericiguat Impurity 89 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 252.25 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
