Overview

N-(PEG1-OH)-N-Boc-PEG2-propargyl is a branched PEG derivative with a terminal hydroxy group, propargyl group, and a Boc protected amino group. The hydroxy group enables further derivatization or replacement with other reactive functional groups. The propargyl group can be reacted with azide-bearing compounds or biomolecules via copper catalyzed azide-alkyne Click Chemistry to yield a stable triazole linkage. The protected amine can be deprotected by acidic conditions.
