Vonoprazan Impurity 175 CAS CATO-C4X-1020175 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Vonoprazan Impurity 175.

CATO supplies Vonoprazan Impurity 175 (CAS CATO-C4X-1020175), a pharmacopoeial impurity reference standard (molecular formula C27H22F2N4O2S, MW 504.55 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C27H22F2N4O2S, Vonoprazan Impurity 175 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 504.55 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.

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.
