N-(Boc-PEG1)-N-bis(PEG2-propargyl)

N-(Boc-PEG1)-N-bis(PEG2-propargyl) is a click chemistry branched linker. The propargyl groups can react with azide-bearing molecule via copper catalyzed Click Chemistry . The Boc group can be deprotected under acidic conditions to release amine group.

N-(Boc-PEG1)-N-bis(PEG2-propargyl) is a PEG-based PROTAC linker that can be used in the synthesis of PROTACs[1]. N-(Boc-PEG1)-N-bis(PEG2-propargyl) is a click chemistry reagent, it contains an Alkyne group and can undergo copper-catalyzed azide-alkyne cycloaddition (CuAAc) with molecules containing Azide groups.
