Description
As a certified reference material (CRM), 7-(Trifluoromethyl)-7,8-dihydroquinazolin-5(6H)-one 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.
CATO supplies 7-(Trifluoromethyl)-7,8-dihydroquinazolin-5(6H)-one (CAS 1420794-79-1), a certified reference material (molecular formula C9H7F3N2O, MW 216.16 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, 7-(Trifluoromethyl)-7,8-dihydroquinazolin-5(6H)-one is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 216.16 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.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
