Chemical Structure
Description
The occurrence of 2-(chlorosulfonyl)-1,3-dimethoxypropane is closely related to a carbohydrate-derived structure, a sulfone group, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 2-(chlorosulfonyl)-1,3-dimethoxypropane (CAS 1871639-57-4), a certified reference material (molecular formula C5H11ClO4S, MW 202.66 g/mol) for analytical method development and quality control.
2-(chlorosulfonyl)-1,3-dimethoxypropane (C5H11ClO4S) contains a carbohydrate-derived structure, a sulfone group, 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.
