Overview

PEG18 contains repeating ethylene glycol subunits and two terminal hydroxyl groups. The hydroxyl groups can participate in reactions to further derivatize the compound. The hydrophilic PEG chain increases the water solubility of the compound in aqueous media. The water solubility properties of the PEG linker are enhanced with longer PEG chains.

HO-PEG17-OH is a PEG-based PROTAC linker that can be used in the synthesis of PROTACs.
