BCN- exo- PEG3- NH2 is a PEG-based PROTAC linker that can be used in the synthesis of PROTACs[1]. BCN- exo- PEG3- NH2 is a click chemistry reagent, it contains a BCN group that can undergo strain-promoted alkyne-azide cycloaddition (SPAAC) with molecules containing Azide groups.

BCN-exo-PEG3-NH2 is a PEG-based PROTAC linker that can be used in the synthesis of PROTACs[1]. PROTACs contain two different ligands connected by a linker; one is a ligand for an E3 ubiquitin ligase and the other is for the target protein. PROTACs exploit the intracellular ubiquitin-proteasome system to selectively degrade target proteins[1].
