Vonoprazan Impurity 246 CAS CATO-C4X-1020246

Description

Compared with other compounds in its class, the molecular weight of 536.59 g/mol gives Vonoprazan Impurity 246 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Vonoprazan Impurity 246 (CAS CATO-C4X-1020246), a pharmacopoeial impurity reference standard (molecular formula C33H27F3N4, MW 536.59 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C33H27F3N4, Vonoprazan Impurity 246 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 536.59 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.

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.
