Chemical Structure

Relebactam Impurity 40 CAS CATO-C4X-214440 chemical structure

Description

Relebactam Impurity 40 (CAS CATO-C4X-214440) is a certified pharmaceutical impurity reference standard with the molecular formula C6H12N2O6S and a molecular weight of 240.23 g/mol.

Relebactam Impurity 40 (C6H12N2O6S) contains a carbohydrate-derived structure, an amide group, a sulfone group. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
