Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-(Dimethylamino)-1-phenyl-2,3-dihydroquinazoline-4(1H)-thione.
CATO supplies 3-(Dimethylamino)-1-phenyl-2,3-dihydroquinazoline-4(1H)-thione (CAS 90070-79-4), a certified reference material (molecular formula C16H17N3S, MW 283.39 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, 3-(Dimethylamino)-1-phenyl-2,3-dihydroquinazoline-4(1H)-thione is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 283.39 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), 3-(Dimethylamino)-1-phenyl-2,3-dihydroquinazoline-4(1H)-thione 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.
