Chiral separation of enantiomers of isoprenaline (with the University of Grenoble)

The isoprenaline racemate is a catecholamine used for the treatment of bradycardia and cardiac arrest. A chiral separation of the two forms is mandatory for the quantification of each enantiomer. In this application note, the Wyn-CE system coupled to non-contact conductivity detection was used for the separation of the two forms of isoprenaline. The effects of pH and Cyclodextrin concentration are described.

L'avis de l'expert : Capillary electrophoresis is a technique of choice for performing chiral analyzes.
