Chemical Structure
Description
CATO supplies N-(4-chloro-1,1-dioxidotetrahydrothiophen-3-yl)acetamide (CAS 201990-56-9), a certified reference material (molecular formula C6H10ClNO3S, MW 211.67 g/mol) for analytical method development and quality control.
N-(4-chloro-1,1-dioxidotetrahydrothiophen-3-yl)acetamide (C6H10ClNO3S) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
