I. [Product Introduction]
SH-PEG-Nitrophenyl Carbonates is a multifunctional organic intermediate. Its molecular structure integrates a highly reactive nitrophenyl carbonate group, a tunable hydrophilic polyethylene glycol (PEG) chain, and a terminal thiol group. It is suitable for polymer modification, bioconjugation, and the construction of catalytic systems. This compound can be used as a pharmaceutical intermediate to build targeted delivery systems or as a catalyst carrier to improve reaction efficiency. Its modular design supports the precise regulation of intermolecular interactions.
