I. [Product Description]
NPC-PEG-HA (Nitrophenyl Carbonate-Polyethylene Glycol-Hyaluronic Acid) is a multifunctional organic intermediate. Through the directional coupling of the active group nitrophenyl carbonate (NPC) with hyaluronic acid (HA), combined with the high biocompatibility and adjustable water-solubility of the PEG chain, it is widely used in the fields of polymer material modification, bioconjugation reactions, and catalyst immobilization. Its modular structural design supports customized molecular weights and functional group ratios, providing an efficient solution for the construction of complex systems.

II. [Product Details]
【Appearance】 Depending on different molecular weights, it appears as a white/off-white solid or a viscous liquid.
【Stability】 Store it in a refrigerator 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 it in a sealed and dry place at a low temperature below 4°C.
▪ Precautions: ▶ To ensure product stability, please open the package for use after constant-temperature drying!

III. [Application Fields]
1. Controllable introduction of active groups and surface functionalization in polymer materials.
2. Hydrophilic modification of nanocarriers and coupling with targeting molecules.
3. Immobilization reaction of enzymes or proteins in biosensors.
4. Cross-linking agent in the preparation of polymer micelles/microspheres.
5. Construction of carriers for metal catalysts in catalytic reaction systems.
