Description
Compared with other compounds in its class, the molecular weight of 287.23 g/mol gives 4-Isopropoxy-2-phenyl-2-(trifluoromethyl)oxazol-5(2H)-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
4-Isopropoxy-2-phenyl-2-(trifluoromethyl)oxazol-5(2H)-one (CAS 124292-93-9) is a high-purity analytical reference standard with the molecular formula C13H12F3NO3 and a molecular weight of 287.23 g/mol.
4-Isopropoxy-2-phenyl-2-(trifluoromethyl)oxazol-5(2H)-one (C13H12F3NO3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, 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. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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), 4-Isopropoxy-2-phenyl-2-(trifluoromethyl)oxazol-5(2H)-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.
