Azido-PEG22-alcohol

Azido-PEG22-alcohol (Azido-PEG22-acid) is a PEG derivative utilized in research areas such as drug delivery. As a click chemistry reagent, it contains an azide group that can undergo a copper-catalyzed azide-alkyne cycloaddition reaction (CuAAc) with molecules containing an alkyne group. Additionally, it can participate in a strain-promoted azide-alkyne cycloaddition reaction (SPAAC) with molecules featuring DBCO or BCN groups.
