6-Ethyl-9-phenyl-2,3-dihydrofuro[2,3-f]quinazolin-7(6H)-one (CAS 61070-71-1), molecular formula C18H16N2O2 and molecular weight 292.33 g/mol, is a CATO reference standard with documented purity and traceability.
6-Ethyl-9-phenyl-2,3-dihydrofuro[2,3-f]quinazolin-7(6H)-one (C18H16N2O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
