Description
As a certified reference material (CRM), 5-Bromo-2-(pyrimidin-5-yl)quinazolin-4-ol 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 5-Bromo-2-(pyrimidin-5-yl)quinazolin-4-ol (CAS 1272356-67-8), a certified reference material (molecular formula C12H7BrN4O, MW 303.11 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, bromine substitution, 5-Bromo-2-(pyrimidin-5-yl)quinazolin-4-ol is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 303.11 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.
