Product Description

HO-PEG-COOtBu is a linear heterobifunctional PEG derivative with one hydroxyl group and one carboxylate tert-butyl ester. The protected carboxyl (COOH) prevents self coupling or polymerization under standard acid/amine or acid/hydroxyl coupling conditions. The protected acid can be regenerated by acidic or basic hydrolysis.
