Azide-PEG3-Sulfone-PEG3-azide is a polyethylene glycol (PEG)-based bifunctional molecule, specifically designed as a PROTAC linker for the synthesis of PROTACs[1].
m-PEG3-Sulfone-PEG3-azide is a polyethylene glycol (PEG)-based linker widely employed in the synthesis of PROTACs, which stands for Proteolysis Targeting Chimeras[1].
