CATO supplies (s)-4-Hydroxy-4-(trifluoromethyl)tetrahydro-2h-pyran-2-one (CAS 956398-58-6), a certified reference material (molecular formula C6H7F3O3, MW 184.11 g/mol) for analytical method development and quality control.
(s)-4-Hydroxy-4-(trifluoromethyl)tetrahydro-2h-pyran-2-one (C6H7F3O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine 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.
As a certified reference material (CRM), (s)-4-Hydroxy-4-(trifluoromethyl)tetrahydro-2h-pyran-2-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.
