Feature of Biphenyl

  • The two benzene rings of the biphenyl group are twisted about 45° and the biphenyl group shows different separation from the phenyl group alone.
  • Even when an aqueous mobile phase containing no organic solvent is used, there is no decrease in retention, and separation with high reproducibility of retention time is achieved.
  • Greater retention of polar compounds such as caffeine.
