Vericiguat Impurity 4 CAS CATO-C4X-28964

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 4.

As a process- or degradation-related impurity, Vericiguat Impurity 4 (CAS CATO-C4X-28964, C18H12F2N8O) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, Vericiguat Impurity 4 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 394.34 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.

As a certified reference material (CRM), Vericiguat Impurity 4 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.
