Silica stationary phase functionalized by 4-carboxy-benzoboroxole with enhanced boronate affinity nature for selective capture and separation of cis-diol compounds

4-Carboxy-benzoboroxole was designed and synthesized. It was then combined with the modification effect of polyethyleneimine (PEI) for the preparation of boronate affinity silica stationary phase. The stationary phase showed improved binding strength with dissociation constant (Kd) towards xanthosin...
