Chemical Structure
Description
The occurrence of 7-Chloro-3-cyclohexyl-2,3-dihydro-2-thioxo-4(1H)-quinazolinone is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 7-Chloro-3-cyclohexyl-2,3-dihydro-2-thioxo-4(1H)-quinazolinone (CAS 731802-55-4), a certified reference material (molecular formula C14H15ClN2OS, MW 294.80 g/mol) for analytical method development and quality control.
Structurally, 7-Chloro-3-cyclohexyl-2,3-dihydro-2-thioxo-4(1H)-quinazolinone (C14H15ClN2OS) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 294.80 g/mol, it falls into the medium-molecular-weight range. 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), 7-Chloro-3-cyclohexyl-2,3-dihydro-2-thioxo-4(1H)-quinazolinone 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.
