3,5-Dimethylbenzo[d]isothiazole 1,1-dioxide CAS 1622159-27-6

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3,5-Dimethylbenzo[d]isothiazole 1,1-dioxide.

3,5-Dimethylbenzo[d]isothiazole 1,1-dioxide (CAS 1622159-27-6), molecular formula C9H9NO2S and molecular weight 195.24 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 3,5-Dimethylbenzo[d]isothiazole 1,1-dioxide (C9H9NO2S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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 manufactures 3,5-Dimethylbenzo[d]isothiazole 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.
