I. [Product Description]
PEI-PEG-SH is a multifunctional organic intermediate that combines the cationic properties of polyethyleneimine (PEI) with the hydrophilic biocompatibility of polyethylene glycol (PEG). Its terminal thiol group (-SH) enables efficient chemical coupling. This compound has important application values in the synthesis of nanomaterials, modification of biological interfaces, and construction of catalytic carriers.
