Propargyl-PEG3-amine is a PEG-based PROTAC linker utilized in the synthesis of PROTACs. It functions as a click chemistry reagent, possessing an alkyne group that can undergo copper-catalyzed azide-alkyne cycloaddition (CuAAc) with molecules containing azide groups. PROTACs use the intracellular ubiquitin-proteasome system to selectively degrade target proteins.

• PEG-based PROTAC linker
• Click chemistry reagent
• Contains an alkyne group for CuAAc reactions with azide groups
