General description
Methoxypolyethylene glycol p-nitrophenyl carbonate is a polyethylene glycol (PEG) derivative. PEGs are widely used as a covalent modifier of biologic macromolecules and particulates and for mechanism of drug delivery.
Application
Methoxypolyethylene glycol p-nitrophenyl carbonate has been used in a study to obtain unimolecular dendritic micelles designed as solubility enhancers. It has also been used in a study to investigate the properties of lipase from Candida rugosa modified with Mpeg. It is also useful for modification of proteins.

Unimolecular dendritic micelles designed as solubility enhancers were obtained by coupling polyethylene glycol (PEG) to Starburst polyamidoamine (PAMAM) dendrimers. Micelles-750, -2000, and -5000 have a generation 3.0 dendrimer core (32 primary amine end groups) and PEG arms with molecular weights

A single-step method of activation of monomethoxypolyethylene glycols suitable for its binding to polypeptides and proteins is proposed. Based on the reaction with 2,4,5-trichlorophenylchloroformate or p-nitrophenylchloroformate, it gives reactive PEG-phenylcarbonate derivatives. The PEG intermediate is stable on storage, the activating
