n-boc-n-bis-peg-5

N-Boc-N-bis-PEG5 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.

N-(Boc-PEG5)-N-bis(PEG4-acid) is a polyethylene glycol (PEG)-derived PROTAC linker employed for PROTAC synthesis[1].
