m-PEG4-azide
m-PEG4-azide is a high-purity monofunctional polyethylene glycol linker terminated with an azide group for copper-catalyzed azide–alkyne cycloaddition (CuAAC) or strain-promoted azide–alkyne cycloaddition (SPAAC) click chemistry. The PEG4 spacer specifically enhances water solubility, flexibility, and reduces steric hindrance, enabling efficient conjugation in both aqueous and organic systems.
