Chemical Structure
Description
CATO supplies 4-(2,4-Dichlorophenyl)-5-(4-methylbenzenesulfinyl)-1,2,3-thiadiazole (CAS 338409-79-3), a certified reference material (molecular formula C15H10Cl2N2OS2, MW 369.29 g/mol) for analytical method development and quality control.
4-(2,4-Dichlorophenyl)-5-(4-methylbenzenesulfinyl)-1,2,3-thiadiazole (C15H10Cl2N2OS2) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; 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.
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), 4-(2,4-Dichlorophenyl)-5-(4-methylbenzenesulfinyl)-1,2,3-thiadiazole 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.
