mPEG-Phosphate

Synonyms: Methoxy polyethylene glycol-Phosphate; PEG with Phosphoric Acid; Methoxy-PEG-Phosphate

Methoxy polyethylene glycol-phosphate (mPEG-Phosphate) is a white solid or viscous liquid whose morphology depends on its molecular weight. It is soluble in most organic solvents and easily soluble in water. mPEG-Phosphate is used to PEG metal oxide particles and surfaces to form a stable monolayer protection, in which the strong binding property of organophosphorus molecules and metal oxides is produced by phosphate-metal coordination interaction to produce stable M-O-P structure. The phosphate-based coupling agent forms a self-assembled monolayer on the surface of metal oxide nanoparticles to form a thermodynamically stable dispersion. It is widely used in medicine research, drug release, nano new materials research, cell culture and other fields.
