I. [Product Description]
COOH-PEG-EPOX Carboxyl-Polyethylene Glycol-Epoxide is a multifunctional organic intermediate that combines the reactivity of carboxyl and epoxy groups. It is widely used in the fields of polymer material modification and bioconjugation. Its PEG segment imparts excellent water solubility and biocompatibility, and it can be used as an efficient catalyst or pharmaceutical intermediate to meet the customized needs of complex synthetic systems.

II. [Product Details]
    【Appearance】 Depending on different molecular weights, it appears as a white/off-white solid or a viscous liquid.
    【Stability】 Store under refrigeration 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 open the package for use only after constant temperature drying!

III. [Application Fields]
    1. Surface functionalization modification of polymer materials (e.g., epoxy group ring-opening reaction).
    2. Targeted modification of nanoparticles or liposomes (carboxyl activation coupling).
    3. Site-specific conjugation and stabilization of proteins or peptides.
    4. Construction of biosensor probes (the PEG segment reduces non-specific adsorption).
    5. Design and synthesis of amphiphilic molecules in organic synthesis.
