Chemical Structure

Relebactam Impurity 73 CAS CATO-C4X-214473 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.

Relebactam Impurity 73 (CAS CATO-C4X-214473) is a certified pharmaceutical impurity reference standard with the molecular formula C16H30N4O3 and a molecular weight of 326.44 g/mol.

Relebactam Impurity 73 (C16H30N4O3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
