I. [Product Description] 
COOH-PEG-Poly-Sarcosines (Carboxyl-Polyethylene Glycol-Polysarcosine) is a multifunctional organic intermediate. The carboxyl group in its molecular structure provides highly efficient reactive sites. The PEG segment endows it with excellent water solubility and biocompatibility, while the polysarcosine part enhances the molecular stability and modifiability. This compound is widely used in the synthesis of biomaterials, the development of polymer catalysts, and the preparation of pharmaceutical intermediates, with high customization potential.
