I. [Product Description] 
COOH-PEG-glutaric acid (Carboxyl-Polyethylene Glycol-Glutaric Acid) is a high-purity organic intermediate with excellent biocompatibility and water solubility. It is widely used in the synthesis of pharmaceutical intermediates and the modification of polymer materials. Its unique bifunctional structure of carboxyl and glutamic acid allows it to serve as an efficient catalyst carrier or molecular linker. Customizable molecular weights are available to meet different experimental needs.

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

III. [Application Fields] 
1. Functional modification of polymer materials (e.g., surface hydrophilicity regulation) 
2. Interface coupling of nanomedicine delivery systems 
3. Directional immobilization of biosensor probe molecules 
4. Controllable coupling of proteins/polypeptide compounds 
5. Construction of amphiphilic molecules in organic synthesis
