I. [Product Description]
COOH-PEG-Dansyl is a high-purity organic intermediate with both carboxyl and dansyl chloride bifunctional groups. It is suitable for biological labeling, surface modification of materials, and the construction of catalytic reaction systems. Its PEG chain provides excellent water solubility and biocompatibility, and is widely used in the synthesis of pharmaceutical intermediates and the development of nanocarriers.

II. [Product Details]
    【Appearance】 Depending on the molecular weight, it appears as a white/off-white solid or a viscous liquid.
    【Stability】 Store under refrigeration and avoid repeated freeze-thaw cycles.
    【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 at a low temperature below 4°C in a sealed and dry environment.
▪ Notes: ▶ To ensure product stability, please open the package for use only after constant temperature drying!

III. [Application Areas]
    1. Synthesis of fluorescent labeling probes (based on the fluorescence properties of dansyl chloride).
    2. Coupling reactions of biological macromolecules (efficient condensation of carboxyl and amino groups).
    3. Surface functionalization modification of nanoparticles (the PEG chain improves dispersibility).
    4. Cross-linking agent for polymer materials (adjust material properties with controllable molecular weight).
    5. Construction of catalytic system carriers (loading metal catalysts for organic synthesis).
