1-[(3,4-Dichlorophenyl)methyl]-6-(4-fluorophenyl)-2-oxo-1,2-dihydropyridine-3-carbonitrile (CAS 252058-80-3), molecular formula C19H11Cl2FN2O and molecular weight 373.21 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-[(3,4-Dichlorophenyl)methyl]-6-(4-fluorophenyl)-2-oxo-1,2-dihydropyridine-3-carbonitrile (C19H11Cl2FN2O) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/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.
CATO manufactures 1-[(3,4-Dichlorophenyl)methyl]-6-(4-fluorophenyl)-2-oxo-1,2-dihydropyridine-3-carbonitrile under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
