The occurrence of 1-(3,5-Dichlorophenyl)-3-phenylurea is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1-(3,5-Dichlorophenyl)-3-phenylurea (CAS 13142-58-0) is a high-purity analytical reference standard with the molecular formula C13H10Cl2N2O and a molecular weight of 281.14 g/mol.
The molecular framework of 1-(3,5-Dichlorophenyl)-3-phenylurea (C13H10Cl2N2O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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-(3,5-Dichlorophenyl)-3-phenylurea 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.
