NH2-PEG3-C1-Boc, also known as PROTAC Linker 5, is a polyethylene glycol (PEG)-based linker utilized in the synthesis of proteolysis targeting chimeras (PROTACs)[1].

N-Boc-C1-PEG3-C3-NH2 is a PEG-based linker for PROTACs which joins two essential ligands, crucial for forming PROTAC molecules. This linker enables selective protein degradation by leveraging the ubiquitin-proteasome system within cells.
