Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 272.22 g/mol gives 1-Isopropyl-6-(trifluoromethyl)-1H,4H-quinoxaline-2,3-dione distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 1-Isopropyl-6-(trifluoromethyl)-1H,4H-quinoxaline-2,3-dione (CAS 242812-07-3), a certified reference material (molecular formula C12H11F3N2O2, MW 272.22 g/mol) for analytical method development and quality control.
1-Isopropyl-6-(trifluoromethyl)-1H,4H-quinoxaline-2,3-dione (C12H11F3N2O2) 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
