ChEBI: A poly(ethylene glycol) terminated with a methyl group at one end. | [Description]
m-PEG36-alcohol(9004-74-4) 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.
| [Brand name]
Carbowax Sentry Methoxypolyethylene Glycol (Union Carbide). | [General Description]
It 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 organics]
Acetone, chloroform, cyclohexanone, dichloromethane, DMF, MEK, toluene (hot), water |
