mPEG-Cl

Methoxy-poly(ethylene glycol)-chloro (mPEG-Cl) is a monofunctional precision PEG derivative with a defined chain length. One end bears a methoxy group. The other end bears a chloro group group. Discrete chain lengths with different degrees of polymerization are available. The chloro terminus can serve as a precursor for suitable nucleophilic substitution reactions to introduce target functional moieties. 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.
