Azido-PEG39-alcohol

Azido-PEG39-alcohol (Azido-PEG39-acid) is a PEG derivative valuable in drug delivery research. As a click chemistry reagent, it features an azide group that allows copper-catalyzed azide-alkyne cycloaddition reactions (CuAAc) with alkyne-containing molecules. Furthermore, it can engage in strain-promoted azide-alkyne cycloaddition reactions (SPAAC) with molecules containing DBCO or BCN groups.
