Cl-PEG-Cl

Alpha,omega-bis(chloro) poly(ethylene glycol) (Cl-PEG-Cl) is a homobifunctional precision PEG derivative with a defined chain length. Both ends bear chloro group groups. Discrete chain lengths with different degrees of polymerization are available. The chloro terminus can serve as a precursor for suitable nucleophilic substitution reactions to introduce target functional moieties. 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.
