I. [Product Description]
NPC-PEG-leucine (Nitrophenyl carbonate-polyethylene glycol-leucine) is a multifunctional organic intermediate with both high coupling activity and excellent water solubility. It is widely used in the synthesis of pharmaceutical intermediates and the modification of polymer materials. Its unique PEG segment can significantly improve the biocompatibility of the product, while the nitrophenyl carbonate group can serve as a highly reactive site, suitable for coupling reaction systems involving catalysts.
