Applications
DescriptionNonaethylene glycol is a polymer consisting of ethylene glycol repeating units and terminal hydroxyl groups. The ethylene glycol units have high water solubility properties. The hydroxyl groups can react in order to further derivatize the compound.
UsesHO-PEG9-OH is used as a reactant in the selective inhibition of human brain tumor cells through quantum-dot-based siRNA delivery.
