I. [Product Description]
    NPC-PEG-HZ Nitrophenyl carbonate-polyethylene glycol-acyl/acyl hydrazide is a multifunctional organic intermediate with both efficient coupling performance and excellent water solubility. In its structure, the nitrophenyl carbonate group can serve as an active site to participate in nucleophilic substitution reactions. The PEG segment endows the molecule with good biocompatibility, and the acyl hydrazide group is suitable for pH-sensitive bonding. It is widely used in the synthesis of pharmaceutical intermediates and the functionalization of polymer materials.
