NH2-PEG1-CH2CH2-Boc

NH2-PEG1-CH2CH2-Boc is a Boc-protected amine-PEG-alkyl linker used in constructing PROTAC molecules for targeted protein degradation. This bifunctional linker facilitates the conjugation of E3 ligase ligands to target protein binders, enabling the development of degraders for both in vitro biochemical studies and in vivo pharmacological research.
