Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2-((2,4-Dichlorobenzyl)thio)-3-phenylquinazolin-4(3H)-one (CAS 329079-91-6), molecular formula C21H14Cl2N2OS and molecular weight 413.32 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C21H14Cl2N2OS, 2-((2,4-Dichlorobenzyl)thio)-3-phenylquinazolin-4(3H)-one contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 413.32 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
