Chemical Structure
Description
CATO supplies N-Methyl-2-(methylamino)ethanesulfonamide hydrochloride (CAS 1820649-90-8), a certified reference material (molecular formula C4H12N2O2SHCl, MW 188.67 g/mol) for analytical method development and quality control.
N-Methyl-2-(methylamino)ethanesulfonamide hydrochloride (C4H12N2O2SHCl) 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.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
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.
