General description

Consisting of eight glucopyranose units arranged in a truncated cone shape, CYCLOBOND II is an excellent chiral selector for multi-ring structures. It is useful for isomeric compounds based on anthracene, chrysene and pyrene type ring structures. CYCLOBOND II offers good selectivity and stability and is applicable to the polar organic mode of separation. Applications include steroids, porphyrins, FMOC amino acids.

  • Bonded phase: Underivatized, native γ-cyclodextrin
