Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 207.25 g/mol gives 4,6-Dimethylbenzo[d]isothiazole-3-carboxylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
4,6-Dimethylbenzo[d]isothiazole-3-carboxylic acid (CAS 1090903-64-2) is a high-purity analytical reference standard with the molecular formula C10H9NO2S and a molecular weight of 207.25 g/mol.
The molecular framework of 4,6-Dimethylbenzo[d]isothiazole-3-carboxylic acid (C10H9NO2S) 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 its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 4,6-Dimethylbenzo[d]isothiazole-3-carboxylic acid 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.
