3-(4-Chloro-2-methylphenyl)-2-{[(2,6-dichlorophenyl)sulfanyl]methyl}-3,4-dihydroquinazolin-4-one (CAS 338959-62-9), molecular formula C22H15Cl3N2OS and molecular weight 461.79 g/mol, is a CATO reference standard with documented purity and traceability.
3-(4-Chloro-2-methylphenyl)-2-{[(2,6-dichlorophenyl)sulfanyl]methyl}-3,4-dihydroquinazolin-4-one (C22H15Cl3N2OS) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; 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.
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.
