Product Information

Description	Propargyl-PEG9-COOtBu is a PEG crosslinker containing a propargyl group and a t-butyl protected carboxyl group. Under the catalysis of copper, propargyl group can react with azide-bearing compounds to produce stable triazole compounds. The hydrophilic PEG spacer increases solubility in aqueous media.
