I. [Product Description]
CHO-PEG-PEI (Aldehyde-Polyethylene Glycol-Polyethyleneimine) is a multifunctional organic intermediate with both high catalytic activity and biocompatibility. Its unique aldehyde functional group and the amphiphilic structure of PEG-PEI make it widely applicable in bioconjugation reactions, polymer material modification, and nanocarrier construction. It is a key material for pharmaceutical intermediate development and catalytic system optimization.

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 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 at a low temperature below 4°C in a sealed and dry environment.
▪ Precautions: ▶ To ensure product stability, please note that the package should be opened for use only after constant temperature drying!

III. [Application Areas]
1. Construction of nanomedicine carriers (based on the cationic properties of PEI and the long-circulation performance of PEG)
2. Surface modification of biosensors (aldehyde-directed coupling of biomolecules)
3. Hydrophilic modification of polymer materials (PEG segments regulate interfacial properties)
4. Site-specific immobilization of proteins/antibodies (specific reaction between aldehyde and amino groups)
5. Construction of heterogeneous catalytic systems (PEI-supported metal nanoparticles)
