What is Dodecaethylene glycol?
Description
PEG13 is a polymer consisting of ethylene glycol subunits with two terminal hydroxyl groups. The hydroxyl groups can undergo reactions to further derivatize the compound. The hydrophilic properties of the PEG linker increases the water solubility properties of attached compounds in aqueous media.
Definition
