I. [Product Description] 
Aminooxy-PEG-PBA (Aminomethyl-polyethylene glycol-phenylboronic acid) is a multifunctional organic intermediate with both efficient coupling ability and biocompatibility. It is widely used in the synthesis of pharmaceutical intermediates and catalytic reaction systems. Its phenylboronic acid group can specifically recognize the cis-diol structure. Combined with the excellent water solubility of the PEG chain, it becomes a key reagent for biomolecule modification and functional material development.
