I. [Product Description]
SS-PEG-NTA (Disulfide bond-Polyethylene glycol-Nitrilotriacetic acid) is a multifunctional organic intermediate with the characteristics of dynamic covalent bond modification, metal ion chelation, and hydrophilic modification. It is widely used in the synthesis of pharmaceutical intermediates and catalyst support systems. Its core value lies in the controllable cleavage through the disulfide bond, combined with the excellent solubility of PEG and the efficient metal coordination ability of NTA, providing a precise solution for material functional modification.

    【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.
    【Solvents】 Conventional organic solvents such as chloroform, dichloromethane, DMSO, etc.
    【Molecular Weight】 (PEG): 2000, 3400, 5000. Other molecular weights can be customized.
    【Storage Conditions】 Store in a sealed and dry place 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 functional modification of polymer materials (such as the construction of dynamic responsive hydrogels)
    2. Metal ion carrier system (based on the chelation and controllable release of transition metals by NTA)
    3. Cross-linker for nano-drug delivery systems (using the disulfide bond to achieve reductive-responsive release)
    4. Conjugation of biosensor probes (enhancing stability and biocompatibility through PEG)
    5. Immobilization of heterogeneous catalysts (directional immobilization of metal catalysts mediated by NTA)
