Chemical Structure
Description
As a certified reference material (CRM), N-(3,5-bis(trifluoromethyl)phenyl)-2-((4-oxo-3,4-dihydroquinazolin-2-yl)thio)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.
N-(3,5-bis(trifluoromethyl)phenyl)-2-((4-oxo-3,4-dihydroquinazolin-2-yl)thio)acetamide (CAS 556787-47-4), molecular formula C18H11F6N3O2S and molecular weight 447.35 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution, N-(3,5-bis(trifluoromethyl)phenyl)-2-((4-oxo-3,4-dihydroquinazolin-2-yl)thio)acetamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 447.35 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
