compound introduction
N-(Boc-PEG1)-N-bis(PEG2-propargyl) is a branched PEG derivative with two terminal propargyl groups and a Boc protected amino group. The propargyl groups can be reacted with azide-bearing compounds or biomolecules via copper catalyzed azide-alkyne Click Chemistry to yield a stable triazole linkage. The Boc group can be deprotected under acidic conditions to release amine group.
