What is Octaethylene glycol?
Description
Octanethylene glycol is a polymer consisting of ethylene glycol monomers and two terminal hydroxyl groups. The PEG chain increases the water solubility of a compound in aqueous media. Increasing the number of ethylene glycol units within the entire chain improves the solubility properties of the PEG linker.
The Uses of Octaethylene glycol
Applications may include: bioconjugation, drug delivery, PEG hydrogel, crosslinker, and surface functionalization
The Uses of Octaethylene glycol
Octaethylene Glycol is part of a leaf extract (Murdannia Bracteata) which was shown to exhibit antioxidant, antimicrobial and anti-cancer properties.Octaethylene Glycol also shows potential application as functional hydraulic fluids.
