5-Chloro-2-[(4-chlorophenyl)methyl]-6-phenyl-2,3-dihydropyridazin-3-one (CAS 861208-88-0) is a high-purity analytical reference standard with the molecular formula C17H12Cl2N2O and a molecular weight of 331.20 g/mol.
The molecular framework of 5-Chloro-2-[(4-chlorophenyl)methyl]-6-phenyl-2,3-dihydropyridazin-3-one (C17H12Cl2N2O) is characterized by a steroid core, 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. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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), 5-Chloro-2-[(4-chlorophenyl)methyl]-6-phenyl-2,3-dihydropyridazin-3-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.
