Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 163.02 g/mol gives chloro(chloromethanesulfonyl)methane distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
chloro(chloromethanesulfonyl)methane (CAS 37557-97-4), molecular formula C2H4Cl2O2S and molecular weight 163.02 g/mol, is a CATO reference standard with documented purity and traceability.
chloro(chloromethanesulfonyl)methane (C2H4Cl2O2S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. 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.
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.
