Summary
The enantiomeric resolution of the methyl ester of β-hydroxy myristic acid by GC on a chiral stationary phase containing derivatized cyclodextrin is described together with the LC separation of the N-phenylureido diethylamide derivative on Chiralcel-OD.
While in gas chromatography the S-enantiomer is eluted first, the order of elution is reversed in liquid chromatography. The structure of the N-phenylureido diethylamide derivative was confirmed by1H-NMR and MS and the separation verified by LC/MS. The excellent resolution obtained with liquid chromatography (α=1.47) allows a detection limit of <0.05% for each enantiomer.
