Azido-PEG3-succinimidyl carbonate

Description

Azido-PEG3-succinimidyl carbonate is a PEG linker that contains azide and succinimdyl carbonate moieties. The azide group can undergo copper-catalyzed Click Chemistry reactions with alkynes. The succinimidyl carbonate group is a good leaving group and commonly reacts with amine nucleophiles. The hydrophilic PEG linker increases the water solubility of the compound.

Uses

Azido-PEG3-O-NHS ester is a PEG-based PROTAC linker that can be used in the synthesis of PROTACs[1]. Azido-PEG3-O-NHS ester 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.
