Description
342621-20-9 N-[4-Chloro-3-(triisopropylsilyloxy)phenyl]-2,2-dimethylpropanamide N-[4-Chloro-3-[[tris(1-methylethyl)silyl]oxy]phenyl]-2,2-dimethylpropanamide (C20H34ClNO2Si) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, 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.
