I. [Product Description] 
    NPC-PEG-COOH (Nitrophenyl carbonate-polyethylene glycol-carboxyl) is a multifunctional organic intermediate with excellent biocompatibility and controllable molecular weight characteristics. The nitrophenyl carbonate group in its structure can serve as a highly efficient activating group, and the carboxyl group facilitates subsequent functional modification. It is widely used in the fields of pharmaceutical intermediate synthesis, polymer material coupling, and catalyst loading.
