I. [Product Description]
PDP-PEG-NH₂ (Pyridyldithio-PEG-Amine) is a multifunctional organic intermediate that combines the dynamic exchange property of disulfide bonds with the biocompatibility of PEG chains. It is widely used in catalyst loading, polymer material modification, and bioconjugation fields. Its pyridyldithio group can achieve controllable cleavage through thiol exchange reaction, and the amino terminal provides an active site for further functionalization. It is a key linking unit for the synthesis of pharmaceutical intermediates and nanomaterials.

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】 Common organic solvents such as chloroform, dichloromethane, and DMSO.
    【Molecular Weight】 (PEG): 2000, 3400, 5000. Other molecular weights can be customized.
    【Storage Conditions】 Store in a sealed, dry condition at a low temperature below 4°C.
▪ Note: ▶ To ensure product stability, please open the package for use only after constant temperature drying!

III. [Application Fields]
    1. Construction of dynamic covalent networks in polymer materials (based on the reversible property of disulfide bonds).
    2. Surface functionalization modification of nanoparticles (by coupling targeting molecules through the amino group).
    3. Controllable immobilization of proteins/enzymes (using the PEG chain to reduce non-specific adsorption).
    4. Construction of intelligent delivery system carriers (responsive release design).
    5. Loading and recovery of transition metal catalysts in organic synthesis.
