Chemical Structure
Description
The occurrence of 1-(2-Chloro-6-fluorobenzyl)-3-((2-chloro-6-fluorobenzyl)oxy)-2-methylpyridin-4(1H)-one is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1-(2-Chloro-6-fluorobenzyl)-3-((2-chloro-6-fluorobenzyl)oxy)-2-methylpyridin-4(1H)-one (CAS 303144-73-2), molecular formula C20H15Cl2F2NO2 and molecular weight 410.24 g/mol, is a CATO reference standard with documented purity and traceability.
1-(2-Chloro-6-fluorobenzyl)-3-((2-chloro-6-fluorobenzyl)oxy)-2-methylpyridin-4(1H)-one (C20H15Cl2F2NO2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
