I. [Product Description]
    SH-PEG-COOH is a bifunctional polyethylene glycol derivative, which combines the high reactivity of thiol (-SH) and carboxyl (-COOH) groups. It can be used as an organic or pharmaceutical intermediate for material surface modification, nanoparticle functionalization, and biomolecule coupling. Its PEG segment provides excellent water solubility and biocompatibility, making it suitable for catalyst support construction and amphiphilic molecule design.

II. [Product Details]
    【Appearance】 It appears as a white/off-white solid or viscous liquid depending on different molecular weights.
    【Stability】 Store it under refrigeration and avoid repeated freeze-thaw cycles.
    【Solvents】 Common organic solvents such as chloroform, dichloromethane, and DMSO.
    【Molecular Weight】(PEG): 2000, 3400, 5000. Other molecular weights can be customized.
    【Storage Conditions】 Store it in a sealed, dry condition at a low temperature below 4°C.
▪ Precautions: ▶ To ensure product stability, please open the package for use only after constant temperature drying!

III. [Application Fields]
    1. Surface functionalization modification of nanomaterials (e.g., directional assembly of gold nanoparticles and quantum dots)
    2. Site-specific coupling and labeling of biomacromolecules (proteins, antibodies)
    3. Synthesis of amphiphilic block copolymers (for micelle or vesicle construction)
    4. Hydrophilic modification of polymer materials and preparation of anti-protein adsorption coatings
    5. Cross-linking agent for functional hydrogels (pH/redox responsive)
