Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-((4-Oxo-3-phenyl-3,4-dihydroquinazolin-2-yl)thio)-N-(4-(trifluoromethoxy)phenyl)acetamide.
2-((4-Oxo-3-phenyl-3,4-dihydroquinazolin-2-yl)thio)-N-(4-(trifluoromethoxy)phenyl)acetamide (CAS 833439-68-2) is a high-purity analytical reference standard with the molecular formula C23H16F3N3O3S and a molecular weight of 471.45 g/mol.
Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution, 2-((4-Oxo-3-phenyl-3,4-dihydroquinazolin-2-yl)thio)-N-(4-(trifluoromethoxy)phenyl)acetamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 471.45 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.
As a certified reference material (CRM), 2-((4-Oxo-3-phenyl-3,4-dihydroquinazolin-2-yl)thio)-N-(4-(trifluoromethoxy)phenyl)acetamide meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
