BocNH-PEG-NHBoc

Alpha,omega-bis(tert-butoxycarbonyl-protected amino) poly(ethylene glycol) (BocNH-PEG-NHBoc) is a homobifunctional precision PEG derivative with a defined chain length. Both ends bear Boc-protected amine groups. Discrete chain lengths with different degrees of polymerization are available. Boc protection separates amine reactions from other synthetic steps. Appropriate deprotection exposes a primary amine for subsequent conjugation. 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.
