Product Description	Propargyl-PEG3-Tos is a PEG derivative containing a tosyl group and a propargyl group. The hydrophilic PEG spacer increases solubility in aqueous media. The tosyl group is a very good leaving group for nucleophilic substitution reactions. 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. Molecular Formula:C₁₄H₁₈O₅S MW:298.4
