Application

3-Aminophenylboronic acid hemisulfate salt is used in the synthesis of:
  • Phenylboronic acid-functionalized inverse opal hydrogels within microfluidic flow cells for glucose sensing.
  • Phenylboronic acid-salicylhydroxamic acid-derived complexing reagent for protein immobilization on chromatographic support.

It can also be used in the preparation of phenylboronic acid (PBA) monolayer-modified Au electrode for the voltammetric sensing of uridine and cytidine.
