Description

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.[1]
• Phenylboronic acid-salicylhydroxamic acid-derived complexing reagent for protein immobilization on chromatographic support.[2]

It can also be used in the preparation of phenylboronic acid (PBA) monolayer-modified Au electrode for the voltammetric sensing of uridine and cytidine.[2]
