OAc-PEG-OAc

Alpha,omega-bis(acetoxy) poly(ethylene glycol) (AcO-PEG-OAc) is a homobifunctional precision PEG derivative with a defined chain length. Both ends bear acetoxy groups. Discrete chain lengths with different degrees of polymerization are available. The acetate temporarily masks the hydroxyl group. Appropriate deprotection restores the opportunity for further hydroxyl derivatization. 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.
