Opis ogólny

Carboxymethyl-β-cyclodextrin, a negatively charged derivative of β-cyclodextrin, is generally used in the chiral analysis of neutral and basic analytes on account of its ability to exhibit counter-current mobility.

Zastosowanie

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.
Carboxymethyl-β-cyclodextrin (CMBCD) is used in the development of recognition and separation technologies to resolve enantiomers based on chiral properties and size. Carboxymethyl-β-cyclodextrin is used in chiral selection and separation by capillary electrophoresis. Carboxymethyl-β-cyclodextrin is used in the development of drug delivery vehicles such as nanocarriers and as a nucleic acid transfection agent.

CE methods with capacitively coupled contactless conductivity detection (C(4)D) were developed for the enantiomeric separation of the following stimulants: amphetamine (AP), methamphetamine (MA), ephedrine (EP), pseudoephedrine (PE), norephedrine (NE) and norpseudoephedrine (NPE). Acetic acid (pH 2.5 and 2.8) was found
