CATO supplies 2-(1,1-Dioxo-1λ6-thiolan-3-yl)ethane-1-sulfonyl chloride (CAS 1018656-49-9), a certified reference material (molecular formula C6H11ClO4S2, MW 246.73 g/mol) for analytical method development and quality control.
2-(1,1-Dioxo-1λ6-thiolan-3-yl)ethane-1-sulfonyl chloride (C6H11ClO4S2) contains 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.
