mPEG-NHMe

Methoxy-poly(ethylene glycol)-methylamino (mPEG-NHMe) is a monofunctional precision PEG derivative with a defined chain length. One end bears a methoxy group. The other end bears a methylamino group. Discrete chain lengths with different degrees of polymerization are available. The secondary amine can participate in suitable acylation or other amine reactions, enabling comparisons of amine substitution and conjugation routes. 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.
