Chemical Structure
Description
The occurrence of Vericiguat Impurity 94 is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Vericiguat Impurity 94 (CAS CATO-C4X-289694) is a certified pharmaceutical impurity reference standard with the molecular formula C20H16F2N8O3 and a molecular weight of 454.39 g/mol.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, Vericiguat Impurity 94 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 454.39 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).
Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.
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.
