7-Chlorobenzo[d]isothiazol-3(2H)-one 1,1-Dioxide CAS 89999-91-7

Description

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.

CATO supplies 7-Chlorobenzo[d]isothiazol-3(2H)-one 1,1-Dioxide (CAS 89999-91-7), a certified reference material (molecular formula C7H4ClNO3S, MW 217.63 g/mol) for analytical method development and quality control.

7-Chlorobenzo[d]isothiazol-3(2H)-one 1,1-Dioxide (C7H4ClNO3S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. 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.

CATO manufactures 7-Chlorobenzo[d]isothiazol-3(2H)-one 1,1-Dioxide under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
