I. [Product Description]
PDLLA(5000)-PEG-COOH is a block copolymer with both amphiphilicity and potential for functional modification. As a high-performance organic intermediate/medical intermediate, its racemic polylactic acid (PDLLA) segment provides biodegradability, the PEG segment enhances water solubility, and the terminal carboxyl group enables directional chemical modification. This compound has important application values in the construction of nanocarriers, catalyst loading, and the synthesis of functional materials.

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.

▪ Note: ▶ To ensure product stability, please open the package for use after constant temperature drying!

III. [Application Fields]
1. Preparation of nanoscale self-assembled micelles/particles (based on the amphiphilicity of PDLLA and PEG)
2. Surface modification of targeted functional material delivery systems (through carboxyl coupling ligands)
3. Synthesis of biocompatible coating materials (combining the degradability of PDLLA and the hydrophilicity of PEG)
4. Construction of recyclable carriers in catalytic reactions (fixing catalytic active sites with carboxyl groups)
5. Modification of polymer materials (adjusting the hydrophilic-hydrophobic balance and reaction sites of materials)
