Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (5E)-5-({2-[3-(trifluoromethyl)phenoxy]phenyl}methylidene)-1,3-thiazolidine-2,4-dione.
CATO supplies (5E)-5-({2-[3-(trifluoromethyl)phenoxy]phenyl}methylidene)-1,3-thiazolidine-2,4-dione (CAS 917607-23-9), a certified reference material (molecular formula C17H10F3NO3S, MW 365.33 g/mol) for analytical method development and quality control.
(5E)-5-({2-[3-(trifluoromethyl)phenoxy]phenyl}methylidene)-1,3-thiazolidine-2,4-dione (C17H10F3NO3S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, 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), (5E)-5-({2-[3-(trifluoromethyl)phenoxy]phenyl}methylidene)-1,3-thiazolidine-2,4-dione 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.
