NH-bis (PEG3-azide)

NH-bis (PEG3-azide) is a PEG-based PROTAC linker that can be used in the synthesis of PROTACs[1]. NH-bis (PEG3-azide) 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.
