Description

(S)-(-)-alpha-Methoxy-alpha-(trifluoromethyl)phenylacetic acid is used as a chiral derivatizing agent, it reacts with an alcohol or amine of unknown stereochemistry to form an ester or amide. The absolute configuration of the ester or amide is then determined by proton and/or 19F NMR spectroscopy.
