Methoxypolyethylene glycols Usage And Synthesis
Descriptionm-PEG36-alcohol is a PEG linker containing a hydroxyl group. The hydroxyl group enables further derivatization or replacement with other reactive functional groups. The hydrophilic PEG spacer increases solubility in aqueous media.
Chemical Propertiesvaries from viscous liquid to white flakes, depending
UsesMethoxypolyethylene Glycol of with an average molecular mass of 350. Methoxypolyethylene Glycol (MPEG) is used in various applications such as micelles for drug delivery as well as in modifications of therapeutic proteins to improve their pharmacokinetics.
Usesenteric coating controlled release and enteric release coatings
UsesMethoxypolyethylene glycol 350 has been used in a study to assess the synthesis of a new class of thermosensitive micellar cyclotriphosphazenes. It has also been used in a study to investigate synthesis of a new amphiphilic poly(organophosphazene) by stepwise nucleophilic substitution.
DefinitionChEBI: A poly(ethylene glycol) terminated with a methyl group at one end.
Brand nameCarbowax Sentry Methoxypolyethylene Glycol (Union Carbide).
General DescriptionIt is a Polyethylene glycol (PEG) macromer with a reactive chain end consisting of methyl ether. Etherification of the PEG chain ends can be undertaken in basic conditions by reacting it with alkyl halides. mPEG can undergo cross linking to form hydrogels; polymerization can be initiated by redox reaction or free radical initiator.
Solubility in organicsAcetone, chloroform, cyclohexanone, dichloromethane, DMF, MEK, toluene (hot), water
