Chemical Structure

Vonoprazan Impurity 243 CAS CATO-C4X-1020243 chemical structure

Description

Vonoprazan Impurity 243 (CAS CATO-C4X-1020243) is a certified pharmaceutical impurity reference standard with the molecular formula C10H8N2S3 and a molecular weight of 252.38 g/mol.

Based on its molecular formula C10H8N2S3, Vonoprazan Impurity 243 contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 252.38 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.

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.
