Chemical Structure
Description
The occurrence of 4-(3-Chloro-5-(trifluoromethyl)pyridin-2-yl)-5-(4-methoxyphenyl)cyclohexane-1,3-dione 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.
4-(3-Chloro-5-(trifluoromethyl)pyridin-2-yl)-5-(4-methoxyphenyl)cyclohexane-1,3-dione (CAS 439110-56-2) is a high-purity analytical reference standard with the molecular formula C19H15ClF3NO3 and a molecular weight of 397.78 g/mol.
4-(3-Chloro-5-(trifluoromethyl)pyridin-2-yl)-5-(4-methoxyphenyl)cyclohexane-1,3-dione (C19H15ClF3NO3) 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. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
