Panoramica
PEG25 contains repeating ethylene glycol subunits with two terminal hydroxyl groups. The hydroxyl groups can be reacted to further derivatize the compound. The hydrophilic PEG linker increases the water solubility of the compound under aqueous environments. The water solubility properties of the PEG linker are enhanced with longer PEG chains.
This compound belongs to the class of organic compounds known as polyethylene glycols. These are oligomers or polymers of ethylene oxide, with the general formula (C2H4O)n (with n>=3).
