Chemical Structure

Nifuratel Impurity 21 CAS CATO-C4X-127221 chemical structure

Description

Based on its molecular formula C5H10N2O3S, Nifuratel Impurity 21 contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 178.21 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

Nifuratel Impurity 21 (CAS CATO-C4X-127221) is a certified pharmaceutical impurity reference standard with the molecular formula C5H10N2O3S and a molecular weight of 178.21 g/mol.

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.
