I. [Product Description]
SS-PEG-SH (Disulfide bond-Polyethylene glycol-Mercapto) is a multifunctional organic intermediate that combines the dynamic reversible cleavage property of the disulfide bond with the biocompatibility of the PEG chain. It is widely used in the surface modification of nanomaterials, polymer cross-linking, and bioconjugation reactions. Its mercapto group (-SH) can efficiently participate in click chemical reactions. Meanwhile, as a pharmaceutical intermediate or catalyst, it shows excellent performance in controlled release systems.

III. [Application Fields]
    1. Surface modification of nanomaterials (e.g., mercapto-directed coupling of gold nanoparticles and quantum dots)
    2. Dynamic cross-linker for stimulus-responsive drug delivery systems (through disulfide bond reduction response)
    3. Site-specific coupling and functional modification of proteins or polypeptides
    4. Construction of reversible cross-linking networks in polymer materials
    5. Functionalization of biosensor interfaces (based on the immobilization reaction of SH groups)
