I. [Product Description] 
DOX-PEG-NPC (Doxorubicin-Polyethylene Glycol-Nitrophenyl Carbonate) is a multifunctional organic intermediate that combines the high reactivity of the NPC group with the biocompatibility advantages of the PEG segment. It is widely used in bioconjugation, polymer material modification, and nanocarrier construction. The adjustable molecular weight of its PEG can precisely meet the requirements of different synthesis scenarios, making it a key linking module in pharmaceutical intermediates and catalytic reactions.
