TETRAETHYLENEGLYCOL MONOMETHYL ETHER Chemical Properties,Uses,Production
Description
m-PEG4-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 Properties
CLEAR COLOURLESS TO VERY SLIGHTLY YELLOW LIQUID
Uses
2,5,8,11-Tetraoxatridecan-13-o1, can be used in the synthesis of various chemicla compounds. It is also a monofunctional PEG that can be used in polymer science.
Definition
ChEBI: 5S,6S-epoxy-15R-hydroxy-ETE is a poly(ethylene glycol).
Synthesis
727986-31-4
23783-42-8
General procedure: Tetraethylene glycol monomethyl ether was synthesized from the compound (CAS: 727986-31-4). This was done as follows: to a solution of 2-(2,5,8,11-tetraoxatridecan-13-yloxy)tetrahydro-2H-pyran (280 mg, 0.96 mmol) in methanol (5 mL) was added pyridinium salt of p-toluenesulfonate (PPTS, 24 mg, 0.096 mmol) at 0 °C. The reaction mixture was slowly warmed from 0 °C to room temperature and stirred for 16 hours. Upon completion of the reaction, the solvent was removed by concentration under reduced pressure to give the crude product. Subsequently, the crude product was purified using silica gel column chromatography with an eluent of 5% methanol/dichloromethane (v/v), resulting in the target compound 5-2A (180 mg, 0.87 mmol, 90% yield) as a pale yellow liquid.
