Chemical Structure
Description
4-Cyano-3,5-difluorophenyl 4'-propyl-[1,1'-bi(cyclohexane)]-4-carboxylate (C23H29F2NO2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
