Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
6-(4-Chlorophenyl)-1-[(3,4-dichlorophenyl)methyl]-4-(methylsulfanyl)-2-oxo-1,2-dihydropyridine-3-carbonitrile (CAS 478042-95-4), molecular formula C20H13Cl3N2OS and molecular weight 435.75 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 6-(4-Chlorophenyl)-1-[(3,4-dichlorophenyl)methyl]-4-(methylsulfanyl)-2-oxo-1,2-dihydropyridine-3-carbonitrile (C20H13Cl3N2OS) is characterized by a steroid core, an amide group, sulfur-containing functionality, 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.
CATO manufactures 6-(4-Chlorophenyl)-1-[(3,4-dichlorophenyl)methyl]-4-(methylsulfanyl)-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.
