I. [Product Description]
HS-PEG-NH2 is a bifunctional polyethylene glycol derivative, which has active reaction sites of sulfhydryl (-SH) and amino (-NH2) groups. It can be used as an organic intermediate or pharmaceutical intermediate for bioconjugation, material surface modification, and nanoparticle functionalization. Its PEG segment endows the molecule with excellent hydrophilicity and biocompatibility, making it suitable for constructing stable molecular bridging systems and having important value in biotechnology research and functional material development.
