Boc-C1-PEG3-C4-OH

Boc-C1-PEG3-C4-OH is an alkyl/ether-based PROTAC linker used to conjugate an E3 ligase ligand to a target protein ligand, enabling the construction of bifunctional molecules for targeted protein degradation. This linker is applied in both in vitro and in vivo PROTAC research to investigate disease-relevant proteins via the ubiquitin-proteasome system.
