As a certified reference material (CRM), 2-Amino-3-(prop-2-yn-1-yl)-5,6,7,8-tetrahydroquinazolin-4(3H)-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.
2-Amino-3-(prop-2-yn-1-yl)-5,6,7,8-tetrahydroquinazolin-4(3H)-one (CAS 3441-94-9), molecular formula C11H13N3O and molecular weight 203.24 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 2-Amino-3-(prop-2-yn-1-yl)-5,6,7,8-tetrahydroquinazolin-4(3H)-one is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 203.24 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.
