Description

Compared with other compounds in its class, the molecular weight of 234.20 g/mol gives 4-Methyl-2H-1,2,4-benzothiadiazin-3(4H)-one-1,1-dioxide sodium salt distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 4-Methyl-2H-1,2,4-benzothiadiazin-3(4H)-one-1,1-dioxide sodium salt (CAS 42140-55-6), a certified reference material (molecular formula C8H7N2O3SNa, MW 234.20 g/mol) for analytical method development and quality control.

4-Methyl-2H-1,2,4-benzothiadiazin-3(4H)-one-1,1-dioxide sodium salt (C8H7N2O3SNa) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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-Methyl-2H-1,2,4-benzothiadiazin-3(4H)-one-1,1-dioxide sodium salt 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.
