Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
6,7-Dimethoxy-2-{[(3-methoxyphenyl)methyl]sulfanyl}-3-{[3-(trifluoromethyl)phenyl]methyl}-3,4-dihydroquinazolin-4-imine (CAS 691868-92-5), molecular formula C26H24F3N3O3S and molecular weight 515.55 g/mol, is a CATO reference standard with documented purity and traceability.
6,7-Dimethoxy-2-{[(3-methoxyphenyl)methyl]sulfanyl}-3-{[3-(trifluoromethyl)phenyl]methyl}-3,4-dihydroquinazolin-4-imine (C26H24F3N3O3S) contains a steroid core, an amide group, a sulfone 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
