Chemical Structure
Description
The occurrence of Avibactam Impurity 3(2R,5S) is closely related to a carbohydrate-derived structure, an amide group, a sulfone group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Avibactam Impurity 3(2R,5S) (CAS 1383814-68-3) is a certified pharmaceutical impurity reference standard with the molecular formula C7H10N3O6SNa and a molecular weight of 287.22 g/mol.
Based on its molecular formula C7H10N3O6SNa, Avibactam Impurity 3(2R,5S) contains a carbohydrate-derived structure, an amide group, a sulfone group; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 287.22 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
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.
