Product Description	Bis-propargyl-PEG2 is a PEG derivative containing two propargyl groups. 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 hydrophilic PEG spacer increases solubility in aqueous media.
