OMs-PEG-OMs

Alpha,omega-bis(methanesulfonate) poly(ethylene glycol) (MsO-PEG-OMs) is a homobifunctional precision PEG derivative with a defined chain length. Both ends bear mesylate groups. Discrete chain lengths with different degrees of polymerization are available. The mesylate provides a handle for nucleophilic substitution, allowing chain-segment construction and installation of the final functional terminus to be performed separately. Identical reactive sites at both ends support molecular bridging or derivatization on both sides. The conjugation scheme can be designed around the number of target sites.
