I. [Product Description]
NPC-PEG-VA Nitrophenyl carbonate-polyethylene glycol-valeric acid is a multifunctional organic intermediate with core values in both pharmaceutical intermediates and polymer material modification. The PEG segment in its structure imparts excellent water solubility and biocompatibility. The nitrophenyl carbonate group can serve as a highly efficient activating group, suitable for coupling reactions or catalyst carrier design. The molecular weight can be customized to meet different application requirements.
