I. [Product Description]
    SH-PEG-VS (Thiol-Polyethylene Glycol-Vinyl Sulfone) is a multifunctional organic intermediate, combining the high reactivity of thiol groups, the hydrophilicity of PEG chains, and the cross-linking properties of vinyl sulfone groups. It is widely used in bioconjugation, material modification, and the construction of catalytic systems. Its molecular structure can be custom-designed to meet the precise requirements for solubility, molecular weight, and reaction sites in different fields.

III. [Application Fields]
    1. Polymer Material Modification: Combine with the surface of metals or polymers through thiol groups to prepare functional coating materials.
    2. Surface Functionalization of Nanoparticles: The PEG chain enhances dispersibility, and the vinyl sulfone group enables the coupling of targeting ligands.
    3. Protein Conjugation Reaction: Act as a cross-linking agent to connect thiol-modified proteins with amino-containing biomolecules.
    4. Biosensor Construction: Utilize the click reaction properties of vinyl sulfone to immobilize biological probe molecules.
    5. Polymer Network Construction: Form a controllable hydrogel system through thiol-vinyl sulfone cross-linking.
