Monodisperse Azido-PEG3-CH2COOtBu (N3-PEG4-CH2COOtBu) is a heterobifunctional PEG molecule containing an azide (N3) group and a t-butyl ester. The azide group readily reacts with alkyne, BCN, DBCO through Click Chemistry to yield a stable triazole linkage. The deprotection of the t-butyl carboxyl group under acidic conditions affords a free carboxylic acid that can be used for coupling with amine-bearing molecules.
