I. [Product Description]
PEI-SS-PEG-COOH is a multifunctional organic intermediate that combines the high molecular weight characteristics of polyethyleneimine (PEI), the redox responsiveness of disulfide bonds (SS), and the biocompatibility of polyethylene glycol (PEG). This compound enables precise modification through the carboxyl group (-COOH) and can serve as a catalyst carrier or a precursor for functionalized materials, with significant application value in the fields of bionanotechnology and polymer synthesis.
