mPEG-OPNP

Methoxy-poly(ethylene glycol)-p-nitrophenyl carbonate (mPEG-OPNP) is a monofunctional precision PEG derivative with a defined chain length. One end bears a methoxy group. The other end bears a p-nitrophenyl carbonate group. Discrete chain lengths with different degrees of polymerization are available. The activated carbonate can react with amine-containing components to form carbamate linkages, providing a linkage distinct from a conventional amide bond. Capping one end defines the direction of derivatization, enabling the hydrophilic PEG segment to be attached to a target molecule and functional linkers of the required length to be constructed.
