Ethyl 1-(5-((4-chlorophenyl)sulfonyl)-4-(2,4-dichlorophenyl)thiazol-2-yl)-5-(trifluoromethyl)-1H-pyrazole-4-carboxylate (CAS 956779-71-8), molecular formula C22H13Cl3F3N3O4S2 and molecular weight 610.84 g/mol, is a CATO reference standard with documented purity and traceability.
Ethyl 1-(5-((4-chlorophenyl)sulfonyl)-4-(2,4-dichlorophenyl)thiazol-2-yl)-5-(trifluoromethyl)-1H-pyrazole-4-carboxylate (C22H13Cl3F3N3O4S2) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/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), Ethyl 1-(5-((4-chlorophenyl)sulfonyl)-4-(2,4-dichlorophenyl)thiazol-2-yl)-5-(trifluoromethyl)-1H-pyrazole-4-carboxylate 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.
