Description
As a certified reference material (CRM), N-{5H,6H-benzo[h]quinazolin-2-yl}-4-fluorobenzamide 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 N-{5H,6H-benzo[h]quinazolin-2-yl}-4-fluorobenzamide (CAS 306979-33-9), a certified reference material (molecular formula C19H14FN3O, MW 319.33 g/mol) for analytical method development and quality control.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, N-{5H,6H-benzo[h]quinazolin-2-yl}-4-fluorobenzamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 319.33 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.
