I. [Product Description]
Chloride-PEG-PASP is a versatile organic intermediate that combines the hydrophilicity of polyethylene glycol (PEG) and the chelating properties of polyaspartic acid (PASP). It can be used as an efficient catalyst carrier or pharmaceutical intermediate. Its modular structure enables precise control of molecular weight and the ratio of functional groups, making it suitable for interface modification and molecular self-assembly in complex synthetic systems.

II. [Product Details]
【Appearance】Depending on the molecular weight, it appears as a white/off-white solid or a viscous liquid.
【Stability】Store it under refrigeration and avoid repeated freeze-thaw cycles.
【Solvents】Common organic solvents such as chloroform, dichloromethane, and DMSO.
【Molecular Weight】(PEG): 2000, 3400, 5000. Other molecular weights can be customized.
【Storage Conditions】Store it in a sealed and 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. Controllable cross-linking agent in polymer material synthesis
2. Surface functionalization modification of nanodrug delivery systems
3. Recyclable template in industrial catalytic reactions
4. Charge调节 component of functional coating materials
5. Development of environmentally friendly water treatment chelating agents
