I. [Product Description]
HS-PEG-PEI (Thiol-Polyethylene Glycol-Polyethyleneimine) is a multifunctional organic intermediate that combines the reactivity of thiol groups, the hydrophilicity of PEG, and the cationic properties of PEI. It exhibits excellent performance in the preparation of pharmaceutical intermediates, the synthesis of polymer materials, and catalytic systems. Its customizable molecular structure makes it an ideal choice for constructing functional composite materials.
