N-(Propargyl-PEG4)-N-bis(PEG4-acid) HCl salt is a branched PEG derivative with a propargyl group and two terminal carboxylic acids. 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 terminal carboxylic acids can be reacted with primary amino groups in the presence of activators (e.g. EDC, or DCC) to form a stable amide bond.
