I. [Product Description]
NPC-PEG-Tosyl (Nitrophenyl carbonate-Polyethylene glycol-Tosyl) is a multifunctional organic intermediate with the characteristics of both pharmaceutical intermediates and polymer modification materials. The Tosyl group and nitrophenyl carbonate group in its structure can serve as highly efficient activation sites, suitable for coupling reactions and the construction of catalyst carriers. The PEG segment provides excellent water solubility and biocompatibility, and the molecular weight can be customized to meet different experimental needs.
