Bis-propargyl-PEG9 is crosslinking reagent containing two propargyl groups. These functional groups enable the formation of triazole linkages with azide-bearing compounds with the presence of copper catalyst. The hydrophilicity of the molecule is improved because of the PEG chain.

Bis-propargyl-peg9 is used as a bivalent estrogen receptor ligand.
