Chemical Structure
Description
5-Methyl-2-phenyl-[1,2,4]triazolo[1,5-a]pyrimidin-7(1H)-one (CAS 36372-09-5) is a high-purity analytical reference standard with the molecular formula C12H10N4O and a molecular weight of 226.23 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 5-Methyl-2-phenyl-[1,2,4]triazolo[1,5-a]pyrimidin-7(1H)-one is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 226.23 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), 5-Methyl-2-phenyl-[1,2,4]triazolo[1,5-a]pyrimidin-7(1H)-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.
