Description
Compared with other compounds in its class, the molecular weight of 426.70 g/mol gives 1-[(2-Chloro-6-fluorophenyl)methyl]-3-[(2,6-dichlorophenyl)methoxy]-2-methyl-1,4-dihydropyridin-4-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1-[(2-Chloro-6-fluorophenyl)methyl]-3-[(2,6-dichlorophenyl)methoxy]-2-methyl-1,4-dihydropyridin-4-one (CAS 338965-33-6) is a high-purity analytical reference standard with the molecular formula C20H15Cl3FNO2 and a molecular weight of 426.70 g/mol.
The molecular framework of 1-[(2-Chloro-6-fluorophenyl)methyl]-3-[(2,6-dichlorophenyl)methoxy]-2-methyl-1,4-dihydropyridin-4-one (C20H15Cl3FNO2) 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
