N-Boc-C1-PEG3-C3-NH2

N-Boc-C1-PEG3-C3-NH2 is a heterobifunctional PEG linker used to construct PROTAC molecules for targeted protein degradation. It connects an E3 ligase ligand to a protein-of-interest ligand, enabling the study of protein function in both cellular and in vivo research models via the ubiquitin-proteasome system.
