I. [Product Description]
Tosyl-PEG-NPC is a multifunctional organic intermediate, combining the high reactivity of the tosyl group with the excellent water solubility and biocompatibility of polyethylene glycol (PEG). This compound can serve as an efficient pharmaceutical intermediate and is suitable for biological conjugation, polymer material modification, and catalyst immobilization. Its nitrophenyl carbonate (NPC) group can specifically react with amino groups to achieve precise molecular coupling.
