I. [Product Description]
Aminooxy-PEG-Bromide (Aminomethyl-polyethylene glycol-bromide, CAS 252378-67-9) is a bifunctional organic intermediate with both aminooxy and bromo reactive groups. It is suitable for biomolecule coupling, polymer material modification, and catalytic reaction systems. Its PEG segment endows the product with excellent water solubility and biocompatibility, making it a key reagent for the synthesis of pharmaceutical intermediates and the development of functional materials.
