Propargyl-PEG1-acid is a PEG analogue containing a propargyl group with a terminal carboxylic acid. The terminal carboxylic acid can reacted with primary amine groups in the presence of activators (e.g. EDC, or DCC) to form a stable amide bond. 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. References:
