N-(Boc-PEG1)-N-bis(PEG2-propargyl) is a branched PEG liner with a terminal hydroxy group and two propargyl groups. The hydroxy group can be derivatized to other reactive functional groups. The propargyl groups readily reacted with azide-bearing compounds or biomolecules via copper catalyzed azide-alkyne Click Chemistry to yield a stable triazole linkage.
