An object is to develop a novel methodology which is excellent for the analysis of enantiomers. The object can be achieved by a method for analyzing an enantiomer including (1) to (3) below:
(1) reacting a mixture of a first compound and a second compound that are a pair of enantiomers with an axially chiral compound that is one of a pair of axially chiral isomers, to generate a derivative mixture containing a first derivative obtained by a reaction of the first compound with the axially chiral compound and a second derivative obtained by a reaction of the second compound with the axially chiral compound;
(2) separating the first derivative and the second derivative in the derivative mixture; and
(3) detecting the separated first derivative and second derivative by mass spectrometry.
Enantiomers may be analyzed by:
(1) reacting a mixture of a first compound and a second compound that are a pair of enantiomers with an axially chiral compound that is one of a pair of axially chiral isomers, to generate a derivative mixture containing a first derivative obtained by a reaction of the first compound with the axially chiral compound and a second derivative obtained by a reaction of the second compound with the axially chiral compound;
(2) separating the first derivative and the second derivative in the derivative mixture; and
(3) detecting the separated first derivative and second derivative by mass spectrometry.
