Abstract: It is found that in the fast atom bombardment(FAB) mass spectra R-α-phenylethylamine and S-α-phenylethylamine can be clearly distinguished by S-1,1'-binaph thyl-2,2'-Jiylhydrogenphosphate(S-BNP).Mixture of R-α-phenylethylamine and S-αphenylethylamine also be tested and the relative abundance of the characteristic ion of mixture is related to the composition of the mixtute.We have therefore proposed a possible method to determine the optical purity of α-phenylethyiamine.

Key words: Enantiomer, Optical purity, Determination by MS
