Collection: Azido PEG

Azido-functionalized PEG derivatives are increasingly finding applications in the realms of conjugation chemistry and targeted drug delivery. Their utility lies in their ability to engage in various chemical reactions, notably copper-catalyzed, ruthenium-catalyzed, and strain-promoted azide-alkyne cycloaddition reactions, yielding triazoles. This convenient and mild click reaction is advantageous for diverse bioconjugation applications. Additionally, the azide group serves as a masked amine, allowing for its reduction to a primary amine through a suitable reducing agent. Furthermore, the Azido group's participation in a Staudinger ligation with appropriate phosphine derivatives enables the creation of water-soluble conjugates, expanding the versatility of these PEG derivatives in targeted drug delivery systems.
