mPEG-NH2

Methoxy-poly(ethylene glycol)-amine (mPEG-NH2) is a monofunctional precision PEG derivative with a defined chain length. One end bears a methoxy group. The other end bears a primary amine group. Discrete chain lengths with different degrees of polymerization are available. The primary amine can react with activated carboxyl groups or NHS esters to form amide bonds and introduce carboxyl-containing 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.
