m-PEG8-azide
m-PEG8-azide is a high-purity monofunctional polyethylene glycol (PEG) derivative featuring a methoxy group on one end and an azide group on the other, connected by a PEG8 spacer. The azide group enables efficient copper-catalyzed azide–alkyne cycloaddition (CuAAC) or strain-promoted azide–alkyne cycloaddition (SPAAC) “click” reactions, providing robust and selective conjugation to alkyne-containing molecules. The PEG8 chain offers excellent hydrophilicity, flexibility, and spacing, making it especially suitable for a wide range of aqueous and organic applications.
