Chemical Structure
Description
The occurrence of 6-Ethyl-2-(5-oxo-3-phenyl-2,5-dihydro-1H-pyrazol-1-yl)-3,4-dihydropyrimidin-4-one is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
6-Ethyl-2-(5-oxo-3-phenyl-2,5-dihydro-1H-pyrazol-1-yl)-3,4-dihydropyrimidin-4-one (CAS 861207-22-9), molecular formula C15H14N4O2 and molecular weight 282.30 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, 6-Ethyl-2-(5-oxo-3-phenyl-2,5-dihydro-1H-pyrazol-1-yl)-3,4-dihydropyrimidin-4-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 282.30 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), 6-Ethyl-2-(5-oxo-3-phenyl-2,5-dihydro-1H-pyrazol-1-yl)-3,4-dihydropyrimidin-4-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.
