Chemical Structure
Description
The occurrence of 4-((2-Oxo-2-(p-tolyl)ethyl)thio)-5,6,7,8-tetrahydroquinazolin-2(1H)-one is closely related to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 4-((2-Oxo-2-(p-tolyl)ethyl)thio)-5,6,7,8-tetrahydroquinazolin-2(1H)-one (CAS 898450-49-2), a certified reference material (molecular formula C17H18N2O2S, MW 314.40 g/mol) for analytical method development and quality control.
Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 4-((2-Oxo-2-(p-tolyl)ethyl)thio)-5,6,7,8-tetrahydroquinazolin-2(1H)-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 314.40 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), 4-((2-Oxo-2-(p-tolyl)ethyl)thio)-5,6,7,8-tetrahydroquinazolin-2(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.
