I. [Product Description] 
VS-PEG-ALK (Vinyl Sulfone-Polyethylene Glycol-Alkyne) is a multifunctional organic intermediate widely used in the synthesis of pharmaceutical intermediates and the cross-linking of polymer materials. Its unique vinyl sulfone group and alkyne group can respectively achieve site-specific coupling and click chemical reactions. Combined with the excellent biocompatibility of the PEG segment, it is an ideal module for constructing functionalized nanocarriers or catalysts.

II. [Product Details] 
    【Appearance】 Depending on different molecular weights, it appears as a white/off-white solid or a viscous liquid. 
    【Stability】 Store refrigerated and avoid repeated freezing and thawing. 
    【Solvent】 Conventional organic solvents such as chloroform, dichloromethane, and DMSO. 
    【Molecular Weight】 (PEG): 2000, 3400, 5000. Other molecular weights can be customized. 
    【Storage Conditions】 Store at a low temperature below 4°C in a sealed and dry environment. 
▪ Precautions: ▶ To ensure product stability, please note that the package can only be opened after constant-temperature drying! 

III. [Application Fields] 
    1. Cross-linking agent for polymer materials (the vinyl sulfone group reacts specifically with amino/mercapto groups). 
    2. Site-specific modification of biomacromolecules (the alkyne group is used for CuAAC/SPAAC click chemical coupling). 
    3. Surface functionalization of nanoparticles (the PEG segment enhances dispersion and stability). 
    4. Construction of metal-organic framework (MOFs) catalyst carriers. 
    5. Development of protein/peptide drug delivery systems.
