1-[(3,4-dichlorophenyl)methyl]-2-oxo-6-phenyl-1,2-dihydropyridine-3-carbonitrile 339108-80-4 9H-440S (CAS 339108-80-4), molecular formula C19H12Cl2N2O and molecular weight 355.22 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-[(3,4-dichlorophenyl)methyl]-2-oxo-6-phenyl-1,2-dihydropyridine-3-carbonitrile 339108-80-4 9H-440S (C19H12Cl2N2O) 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. 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.
