Beschreibung

General description

Succinyl-β-cyclodextrin is a negatively charged cyclodextrin derivative that has major implications in the chiral separation of neutral and basic analytes by means of capillary electrophoresis (CE), owing to its counter-current mobility.

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.
Succinyl-β-cyclodextrin and carboxymethyl-β-cyclodextrin are used as chiral selective agents in capillary electrophoresis for the separation of di- and tri-peptide enantiomers and catechin enantiomers. Succinyl-β-cyclodextrin is used to optimize analysis of PNA-DNA duplexes with diethylthiadicarbocyanine dye.

Succinyl-β-cyclodextrin may be used as a chiral selector to resolve:

• Acylamine fungicides in commercial agrochemical formulations by electrokinetic chromatography (EKC).[1]
• Catechin isomers[2] in human biological samples and antihistamines in pharmaceutical preparations by CE.
