I. [Product Description]
Mal-PEG-PEI is a multifunctional organic intermediate that enables efficient thiol click chemistry modification through maleimide groups. It combines the excellent water solubility of polyethylene glycol (PEG) and the high loading capacity of polyethyleneimine (PEI). This compound can be used as a pharmaceutical intermediate or catalyst carrier and is widely applied in the fields of bioconjugation, nanomaterial synthesis, and functional surface modification.
