Product Description

Amine-PEG-COOtBu (NH2-PEG-COOtBu) is a linear heterobifunctional PEG derivative with one aine 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.
