I. [Product Description]
SS-PEG-NH₂ (Disulfide bond-Polyethylene glycol-Amino group) is a multifunctional organic intermediate. It realizes controllable degradation characteristics through the disulfide bond and is widely used in the fields of bioconjugation, polymer material modification, and nanocarrier preparation. Its polyethylene glycol (PEG) segment provides excellent hydrophilicity and biocompatibility, and the amino-terminal supports efficient chemical modification. It is the core raw material for the synthesis of pharmaceutical intermediates and the development of functional materials.
