mPEG-Propargyl

Methoxy-poly(ethylene glycol)-propargyl ether (mPEG-Propargyl) is a monofunctional precision PEG derivative with a defined chain length. One end bears a methoxy group. The other end bears a propargyl ether group. Discrete chain lengths with different degrees of polymerization are available. The propargyl ether retains a terminal alkyne and an ether linkage, enabling target functional moieties to be introduced through azide–alkyne click reactions. 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.
