Azido-PEG4-4-nitrophenyl carbonate（Cat No.:I015765）is a heterobifunctional reagent designed for efficient and selective bioconjugation. It contains a terminal azide group for copper-catalyzed or strain-promoted click chemistry with alkynes, and a reactive 4-nitrophenyl carbonate moiety that couples readily with hydroxyl or amine groups to form stable linkages. The PEG4 spacer enhances solubility, flexibility, and reduces steric hindrance, ensuring accessibility in complex biological environments. This reagent is widely applied in probe development, surface functionalization, proteomics, and drug discovery, offering precise and versatile conjugation strategies for chemical biology and materials science research.
