The invention describes new chiral stationary phases containing a 4-amino-3,5-dinitrobenzoic unit modified with chiral groups and spacer groups. The invention includes the process for the perparation of said stationary phases starting from 4-halogenated derivative of 3,5-dinitrobenzoic acid, chiral selectors obtainable as intermediates in the aforesaid process, and the use of the chiral stationary phases in the separation of enantiomers.
