Application

Cyclodextrins (CD) are cyclic oligosaccharides composed of D-glucose units connected via α(1→4) glycosidic bonds. Common cyclodextrins contain six (α-CD); seven (β-CD) or eight (gamma-CD) D-glucose units. Cyclodextrins are sometimes derivitized through esterification at positions two, three and/or six.(2-Carboxyethyl)-β-cyclodextrin and other negative charge derivitized cyclodextrins are used in chiral recognition and resolution of cationic racemic mixtures of enantiomers using capillary electrophoresis.
