I. [Product Description]
Tosyl-PEG-PEI (Tosyl-Polyethylene Glycol-Polyethyleneimine) is a multifunctional organic intermediate with both reactivity and biocompatibility. It is widely used in the fields of polymer coupling, nanomaterial modification, and catalyst loading. The high reactivity of the tosyl group, the hydrophilicity of the PEG segment, and the cationic properties of PEI in its molecule make it an ideal choice for surface functionalization and composite preparation.
