Chemical Structure
Description
2-((2,4-Dichlorobenzyl)thio)-3-isobutylquinazolin-4(3H)-one (CAS 329779-74-0), molecular formula C19H18Cl2N2OS and molecular weight 393.33 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution, 2-((2,4-Dichlorobenzyl)thio)-3-isobutylquinazolin-4(3H)-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 393.33 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
