Overview
PEG22 is a polymeric structure consisting of ethylene glycol units and two terminal hydroxyl groups. The hydroxyl group can be reacted to further derivatize the compound. The hydrophilic PEG linkers increase the water solubility of the compound in aqueous media. The water solubility properties of the PEG linker are enhanced with longer PEG chains.
