  • Product Information
I. [Product Description]
DTPA-PEG-NTA is a multifunctional organic intermediate that combines the strong metal chelating ability of diethylenetriaminepentaacetic acid (DTPA) with the excellent water solubility and biocompatibility of polyethylene glycol (PEG). It is suitable for metal ion loading, polymer material modification, and catalytic system construction. Its nitrilotriacetic acid (NTA) group can directionally bind transition metals and is widely used in the synthesis of pharmaceutical intermediates and ligand design in catalytic reactions.

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 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.
▪ Note: ▶ To ensure product stability, please open the package for use only after constant-temperature drying!

III. [Application Fields]
    1. Construction of metal ion chelation systems (e.g., Ni²⁺, Co²⁺ coordination for protein purification carriers)
    2. Surface functionalization of nanomaterials (coating of quantum dots/magnetic particles)
    3. Graft modification of high molecular polymers (enhancing water solubility and stability of materials)
    4. Directional immobilization of metal catalysts in catalytic reactions
    5. Metal coordination carriers in bioconjugation technology
