Chemical Structure
Description
4-(2,4-Dichlorophenyl)-5-(methylsulfonyl)-1,2,3-thiadiazole (CAS 1708199-38-5) is a high-purity analytical reference standard with the molecular formula C9H6Cl2N2O2S2 and a molecular weight of 309.19 g/mol.
4-(2,4-Dichlorophenyl)-5-(methylsulfonyl)-1,2,3-thiadiazole (C9H6Cl2N2O2S2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. 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.
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-(methylsulfonyl)-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.
