Boc-Aminooxy-PEG4-Tos is a PEG compound with two different functional groups (also known as heterobifunctional). Unlike homobifunctional PEG compounds (same functional group on both ends), this type of compounds are more versatile as have two different anchor points. Boc-Aminooxy-PEG4-Tos is used as a linker and spacer to add a PEG moiety, via pegylation (a bioconjugation technique) to proteins, peptides, oligonucleotides, small molecules and nanoparticles.

Boc-Aminooxy-PEG4-Tos is a PEG-based linker for PROTACs which joins two essential ligands, crucial for forming PROTAC molecules.
