I. [Product Description]
NH2-PEG-SS (Amino-polyethylene glycol-disulfide bond) is a multi-functional organic intermediate with potential applications as both a pharmaceutical intermediate and a catalyst carrier. Its unique disulfide bond (SS) structure endows it with redox-responsive properties, making it suitable for constructing intelligent delivery systems. The synergistic effect of the amino group (NH2) and the polyethylene glycol (PEG) chain can significantly enhance biocompatibility and water solubility, meeting the requirements for precise chemical modification.

II. [Product Details]
【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 freeze-thaw cycles.
【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 in a sealed, dry place 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. Preparation of nano drug carriers (utilizing the disulfide bond for intracellular redox-responsive release).
2. Protein/polypeptide coupling reactions (directional modification with amino active groups).
3. Construction of targeted biological probes (the PEG chain enhances in vivo circulation stability).
4. Functionalization of polymer materials (regulating the balance of hydrophilicity and hydrophobicity and interfacial properties).
5. Development of reversible cross-linked hydrogels (based on the dynamic bonding mechanism of the disulfide bond).
