General description

(2-Hydroxyethyl)-β-cyclodextrin is a chemically modified, hydroxyalkylated derivative of cyclodextrin that finds potential use mainly in cosmetics application.

Application

(2-Hydroxyethyl)-β-cyclodextrin may be used as a chiral selector to resolve cathinone derivatives, lactic acid and oxybutynin enantiomers by capillary electrophoresis (CE), and high performance liquid chromatography (HPLC) techniques.

Methcathinone (ephedrone), 4-methylmethcathinone (mephedrone), and 3-methylmethcathinone (metaphedrone) are toxicologically-important cathinone derivatives used commonly as designer drugs. In this work we show the first method allowing to separate simultaneously all these molecules in a chiral medium, ensuring good resolution between all
