I. [Product Description]
COOH-PEG-NCO (Carboxy-Polyethylene Glycol-Isocyanate) is a multifunctional organic intermediate with both excellent biocompatibility and high reactivity. The isocyanate group (-NCO) in its molecule can serve as an efficient catalyst or cross-linking agent, and is widely used in the fields of polymer material synthesis and surface modification. The PEG segment endows the product with good water solubility, making it an ideal choice for the development of pharmaceutical intermediates and the preparation of functional materials.
