Description

Compared with other compounds in its class, the molecular weight of 431.53 g/mol gives 2-(2,3-Dibromo-4-chlorobutyl)benzo[d]isothiazol-3(2H)-one 1,1-dioxide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 2-(2,3-Dibromo-4-chlorobutyl)benzo[d]isothiazol-3(2H)-one 1,1-dioxide (CAS 866156-19-6), a certified reference material (molecular formula C11H10Br2ClNO3S, MW 431.53 g/mol) for analytical method development and quality control.

2-(2,3-Dibromo-4-chlorobutyl)benzo[d]isothiazol-3(2H)-one 1,1-dioxide (C11H10Br2ClNO3S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine/bromine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), 2-(2,3-Dibromo-4-chlorobutyl)benzo[d]isothiazol-3(2H)-one 1,1-dioxide meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
