mPEG-N3

Methoxy-poly(ethylene glycol)-azido (mPEG-N3) is a monofunctional precision PEG derivative with a defined chain length. One end bears a methoxy group. The other end bears an azide group. Discrete chain lengths with different degrees of polymerization are available. The azide can undergo copper-catalyzed click reactions with terminal alkynes or copper-free click conjugation with strained alkynes such as DBCO and BCN. 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.
