I. [Product Description]
NPC-PEG-tyrosine (Nitrophenyl carbonate-polyethylene glycol-tyrosine) is a multifunctional organic intermediate that combines the high reactivity of nitrophenyl carbonate (NPC) with the excellent water solubility and biocompatibility of polyethylene glycol (PEG). This compound, used as a pharmaceutical intermediate or catalyst, is widely applied in bioconjugation reactions and polymer material synthesis. Its modular design supports flexible regulation of molecular weight to meet different experimental needs.
