As a certified reference material (CRM), 3-Oxo-2-(trifluoromethylthio)butyric acid ethylester 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.
3-Oxo-2-(trifluoromethylthio)butyric acid ethylester (CAS 42105-37-3) is a high-purity analytical reference standard with the molecular formula C7H9F3O3S and a molecular weight of 230.20 g/mol.
3-Oxo-2-(trifluoromethylthio)butyric acid ethylester (C7H9F3O3S) contains a sulfone group, 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
