CATO supplies 1-(5-{[3-chloro-5-(trifluoromethyl)pyridin-2-yl]methyl}thiophen-2-yl)-2-{[5-(pyridin-3-yl)-1,3,4-oxadiazol-2-yl]sulfanyl}ethan-1-one (CAS 339016-53-4), a certified reference material (molecular formula C20H12ClF3N4O2S2, MW 496.91 g/mol) for analytical method development and quality control.
1-(5-{[3-chloro-5-(trifluoromethyl)pyridin-2-yl]methyl}thiophen-2-yl)-2-{[5-(pyridin-3-yl)-1,3,4-oxadiazol-2-yl]sulfanyl}ethan-1-one (C20H12ClF3N4O2S2) contains a steroid 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), 1-(5-{[3-chloro-5-(trifluoromethyl)pyridin-2-yl]methyl}thiophen-2-yl)-2-{[5-(pyridin-3-yl)-1,3,4-oxadiazol-2-yl]sulfanyl}ethan-1-one 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.
