Chemical Structure
Description
Based on its molecular formula C23H19N9, Vericiguat Impurity 77 contains a nitrogen-containing heterocyclic scaffold, a nitrile group; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 421.46 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
CATO supplies Vericiguat Impurity 77 (CAS CATO-C4X-289677), a pharmacopoeial impurity reference standard (molecular formula C23H19N9, MW 421.46 g/mol) used for the identification and quantification of trace impurities in APIs.
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 77 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.
