Sugammadex Impurity 33 CAS CATO-C4X-190633

Description

The occurrence of Sugammadex Impurity 33 is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Sugammadex Impurity 33 (CAS CATO-C4X-190633) is a certified pharmaceutical impurity reference standard with the molecular formula C70H103O46S8Na and a molecular weight of 1960.02 g/mol.

Based on its molecular formula C70H103O46S8Na, Sugammadex Impurity 33 contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 1960.02 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.
