Vonoprazan Impurity 278 CAS CATO-C4X-1020278

Description

Compared with other compounds in its class, the molecular weight of 347.41 g/mol gives Vonoprazan Impurity 278 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Vonoprazan Impurity 278 (CAS CATO-C4X-1020278), a pharmacopoeial impurity reference standard (molecular formula C17H18FN3O2S, MW 347.41 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C17H18FN3O2S, Vonoprazan Impurity 278 contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 347.41 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.

CATO manufactures Vonoprazan Impurity 278 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
