General description

On CYCLOBOND I 2000 SP, the hydroxyl groups on the surface of the β-cyclodextrin have been reacted with (S)-propylene oxide. This has the effect of extending hydrogen-bonding capabilities to accommodate analytes with chiral centers that are relatively distant from an aromatic ring structure. The (S)- form shows enhanced selectivity and efficiency for some separations, methadone, for example.
