Chemical Structure
Description
Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution, Vonoprazan Impurity 162 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 472.51 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
As a process- or degradation-related impurity, Vonoprazan Impurity 162 (CAS CATO-C4X-1020162, C21H17FN4O4S2) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.
This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.
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.
