Chemical Structure
Description
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.
As a process- or degradation-related impurity, Fudosteine Impurity 23 HCl (CAS CATO-C4X-144723, C6H13NO3S2HCl) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.
Fudosteine Impurity 23 HCl (C6H13NO3S2HCl) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
