I-PEG-I

Alpha,omega-bis(iodo) poly(ethylene glycol) (I-PEG-I) is a homobifunctional precision PEG derivative with a defined chain length. Both ends bear iodo group groups. Discrete chain lengths with different degrees of polymerization are available. The iodo terminus can be used in suitable nucleophilic substitution routes, enabling comparisons of different halogenated linker precursors and their derivatives. 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.
