As a certified reference material (CRM), 1-[2-(Diethylamino)ethyl]-4-sulfanylidene-1,2,3,4,5,6,7,8-octahydroquinazolin-2-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.
1-[2-(Diethylamino)ethyl]-4-sulfanylidene-1,2,3,4,5,6,7,8-octahydroquinazolin-2-one (CAS 920250-50-6) is a high-purity analytical reference standard with the molecular formula C14H23N3OS and a molecular weight of 281.42 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, 1-[2-(Diethylamino)ethyl]-4-sulfanylidene-1,2,3,4,5,6,7,8-octahydroquinazolin-2-one is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 281.42 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.
