Chemical Structure

Avibactam impurity 153 CAS CATO-C4X-1348153 chemical structure

Description

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.

Avibactam impurity 153 (CAS CATO-C4X-1348153) is a certified pharmaceutical impurity reference standard with the molecular formula C7H10N3O6SNa and a molecular weight of 287.22 g/mol.

Owing to a carbohydrate-derived structure, an amide group, a sulfone group, Avibactam impurity 153 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 287.22 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
