I. [Product Description]
VS-PEG-CHO (Vinyl Sulfone-Polyethylene Glycol-Aldehyde) is a multifunctional organic intermediate that combines the high reactivity of vinyl sulfone groups with the directional coupling ability of aldehyde groups. It is suitable for precise coupling reactions in fields such as protein modification, nanomaterial synthesis, and bioconjugation. Its PEG segment can significantly enhance the water solubility and biocompatibility of the product, making it an ideal catalyst carrier for developing high-performance composite materials.

III. [Application Areas]
    1. Site-specific conjugation modification of proteins (specific binding of vinyl sulfone groups to thiol groups).
    2. Surface functionalization of nanoparticles (covalent cross-linking of aldehyde groups with amino groups).
    3. Construction of biosensor probes (PEG chains enhance stability).
    4. Cross-linking agent for polymer materials (controlled molecular weight regulates reaction efficiency).
    5. Development of drug delivery systems (PEGylation improves drug-loading performance).
