I. [Product Description]
VS-PEG-EPOX is a multifunctional organic intermediate. Through the synergistic effect of vinyl sulfone groups (VS) and epoxides (EPOX), combined with the excellent water solubility and biocompatibility of the polyethylene glycol (PEG) segment, it is widely used in the fields of bioconjugation and material surface modification. Its modular structure design supports precise and controllable molecular weight customization, and it is a key raw material for the development of pharmaceutical intermediates and the preparation of polymer catalyst carriers.

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

III. [Application Areas]
    1. Directional conjugation of proteins/antibodies with nanoparticles (based on the specific reaction between vinyl sulfone and thiol groups).
    2. Surface hydrophilic modification of functionalized polymer materials (the PEG segment reduces non-specific adsorption).
    3. Preparation of porous material-supported catalysts (the epoxide group covalently cross-links with the carrier).
    4. Immobilization of biosensor probes on microfluidic chips.
    5. Design of functional linking arms for polymer drug delivery systems.
