2-[2-(2-Azidoethoxy)ethoxy]ethanol

Azido-PEG3-alcohol is a click chemistry PEG linker containing an azide group and a terminal hydroxyl group. The azide group is reactive with alkyne, BCN, DBCO via Click Chemistry to yield a stable triazole linkage. The hydroxyl group enables further derivatization or replacement with other reactive functional groups.

Azido-PEG3-alcohol is a PEG-based PROTAC linker can be used in the synthesis of PROTACs[1]. Azido-PEG3-alcohol is a click chemistry reagent, it contains an Azide group and can undergo copper-catalyzed azide-alkyne cycloaddition reaction (CuAAc) with molecules containing Alkyne groups. It can also undergo strain-promoted alkyne-azide cycloaddition (SPAAC) reactions with molecules containing DBCO or BCN groups.
