General description

The hydroxyl groups on the surface of the β-cyclodextrin are reacted with (R,S)-propylene oxide to yield a general purpose chiral stationary phase. It has the added property of separating non-aromatic structures such as t-boc amino acids, for which it is a standard methodology.

  • Bonded phase: (R,S)-Hydroxypropyl modified β-cyclodextrin

Application

Astec® CYCLOBOND I 2000 RSP chiral HPLC column is basically comprised of native and derivatized β and γ cyclodextrins.[1] It has been used for numerous chiral separations via selectively trapping the organic molecules in the cyclodextrin cavity.[1]
