HO-PEG-VinylEther

Alpha-(hydroxy)-omega-(vinyl ether) poly(ethylene glycol) (HO-PEG-VinylEther) is a heterobifunctional precision PEG derivative with a defined chain length. The two ends bear hydroxyl and vinyl ether groups, respectively. Discrete chain lengths with different degrees of polymerization are available. The terminal hydroxyl group can be further modified by esterification, etherification, or other functional-group transformations. The vinyl ether retains a double bond available for polymerization or addition in compatible chain-segment polymerization and functionalization routes. The two end groups can be coupled sequentially using compatible reactions and appropriate protection strategies, enabling surface immobilization, functional-molecule bridging, and directional spacer synthesis.
