CHROMATOGRPHIC STATIONARY PHASE FOR SEPARATION OF CYCLODEXTRINE DERIVATIVES THEREOF

The present invention relates to chromatographic stationary phase characterized by the general formula M-BG-SP-SE, wherein M is a chromatographic carrier matrix; BG is a group of (Z)3Si, wherein Z is, hydroxyl, alkyl, alkoxy group or a bond binding to M; SP is optionally substituted C1-6 alkylene, SE is -W-R2-Ar, wherein W is -NH-CO-NH-, -NH-CO- or -NH-CO-O-, R2 is optionally substituted C1-6 alkylene, Ar is C5-16 optionally substituted aromatic group optionally containing O-, N- and S-atoms; with the proviso that if SP is propylene and Ar is phenyl optionally substituted with -NO2, then W is different from -NH-CO-. Further subjects of this invention are the use of the above stationary phases, the starting compounds applied in the preparation of the characteristic surface of the above stationary phases and the use thereof.
