Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-(2-Oxo-1-phenyl-5-thioxo-3-(m-tolyl)imidazolidin-4-ylidene)-3-(m-tolyl)urea.
1-(2-Oxo-1-phenyl-5-thioxo-3-(m-tolyl)imidazolidin-4-ylidene)-3-(m-tolyl)urea (CAS 79174-50-8) is a high-purity analytical reference standard with the molecular formula C24H20N4O2S and a molecular weight of 428.51 g/mol.
Based on its molecular formula C24H20N4O2S, 1-(2-Oxo-1-phenyl-5-thioxo-3-(m-tolyl)imidazolidin-4-ylidene)-3-(m-tolyl)urea contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 428.51 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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), 1-(2-Oxo-1-phenyl-5-thioxo-3-(m-tolyl)imidazolidin-4-ylidene)-3-(m-tolyl)urea 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.
