Chemical Structure
Description
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.
Avibactam Impurity 31 (CAS CATO-C4X-134831) is a certified pharmaceutical impurity reference standard with the molecular formula C7H8N2O7SNa and a molecular weight of 287.20 g/mol.
Owing to a carbohydrate-derived structure, an amide group, a sulfone group, Avibactam Impurity 31 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 287.20 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.
