| PENTAETHYLENE GLYCOL Usage And Synthesis |
| Description | Pentaethylene 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. | | Chemical Properties | colourless liquid | | Uses | Intermediate in the synthesis of cyclic and noncyclic polyethers, complexing agents and immobilized phase-transfer catalysts | | Uses | Pentaethylene glycol is part of a group of compounds called polyethylene glycols (PEGs), which are major byproducts of non-ionic surfactants biodegradation. Pentaethylene glycol is a useful synthetic intermediate, and is used as a reagent to synthesize macrocyclic oligoesters through lipase-catalysis. | | Synthesis Reference(s) | Synthetic Communications, 16, p. 19, 1986 DOI: 10.1080/00397918608057683 |
