2-(3,4-Dichlorophenyl)isothiazolidine 1,1-dioxide (CAS 701305-11-5), molecular formula C9H9Cl2NO2S and molecular weight 266.14 g/mol, is a CATO reference standard with documented purity and traceability.
2-(3,4-Dichlorophenyl)isothiazolidine 1,1-dioxide (C9H9Cl2NO2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone 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.
