I. [Product Description]
NPC-PEG-Poly-Arginines is a multifunctional organic intermediate composed of a nitrophenyl carbonate (NPC) reactive group, a polyethylene glycol (PEG) segment, and a polyarginine (Poly-Arginines) functional unit, combining high coupling ability and biocompatibility. The PEG segment in its structure can significantly enhance water solubility and stability. It is widely used in the synthesis of pharmaceutical intermediates and the development of biological materials, and can also be used as a catalyst carrier in specific reaction systems.
