Chiral resolving agents for enantioseparations

Abstract

A cyclodextrin composition of substantially pure, sulfated-cyclodextrin derivatives particularly suitable as chiral resolving agents for enantioseparation by electrophoresis. The cyclodextrin composition preferably have an isomeric purity of at least 80 mole %. Non-sulfato substituents for the substantially pure cyclodextrin derivatives are hydrogen, C1-C12 alkyl groups, C2-C8 hydroxyalkyl groups, C1-C12 alkylnitryl groups, C2-C12 acyl groups, aryl groups, carbamate groups, thiocarbamate groups or combinations thereof.
