mPEG-OAc

Methoxy-poly(ethylene glycol)-acetoxy (mPEG-OAc) is a monofunctional precision PEG derivative with a defined chain length. One end bears a methoxy group. The other end bears a acetoxy group. Discrete chain lengths with different degrees of polymerization are available. The acetate temporarily masks the hydroxyl group. Appropriate deprotection restores the opportunity for further hydroxyl derivatization. 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.
