Description and Uses
Heptaethylene glycol contains repeating ethylene glycol subunits and two terminal hydroxyl groups. The hydroxyl groups can react to further derivatize the compound. The hydrophilic PEG linker increases the water solubility of a compound in aqueous media. The water solubility properties of the PEG linker are enhanced with longer PEG chains.
Heptaethylene Glycol is used for the preparation of large ring crown ether compounds.
