mPEG-NHBoc

Methoxy-poly(ethylene glycol)-tert-butoxycarbonyl-protected amino (mPEG-BocNH) is a monofunctional precision PEG derivative with a defined chain length. One end bears a methoxy group. The other end bears a Boc-protected amine group. Discrete chain lengths with different degrees of polymerization are available. Boc protection separates amine reactions from other synthetic steps. Appropriate deprotection exposes a primary amine for subsequent conjugation. 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.
