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 200.
Vonoprazan Impurity 200 (CAS CATO-C4X-1020200) is a certified pharmaceutical impurity reference standard with the molecular formula C5H8N2O5 and a molecular weight of 176.13 g/mol.
Owing to a carbohydrate-derived structure, an amide group, Vonoprazan Impurity 200 is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 176.13 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).
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.
