Chemical Structure

Sugammadex Impurity 43 CAS 1378831-29-8 chemical structure

Description

The occurrence of Sugammadex Impurity 43 is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Sugammadex Impurity 43 (CAS 1378831-29-8), a pharmacopoeial impurity reference standard (molecular formula C6H10O3S2, MW 194.27 g/mol) used for the identification and quantification of trace impurities in APIs.

Sugammadex Impurity 43 (C6H10O3S2) contains a sulfone group, a carboxylic acid 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.

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.
