Description

Compared with other compounds in its class, the molecular weight of 337.80 g/mol gives 2-Methyl-4-(4-methyl-1,1-dioxido-3-oxoisothiazolidin-2-yl)benzenesulfonyl chloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-Methyl-4-(4-methyl-1,1-dioxido-3-oxoisothiazolidin-2-yl)benzenesulfonyl chloride (CAS 927997-24-8) is a high-purity analytical reference standard with the molecular formula C11H12ClNO5S2 and a molecular weight of 337.80 g/mol.

2-Methyl-4-(4-methyl-1,1-dioxido-3-oxoisothiazolidin-2-yl)benzenesulfonyl chloride (C11H12ClNO5S2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone 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.

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.
