Product Information

Description	Propargyl-PEG6-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.
Synonyms	Propargyl-PEG6-t-butyl ester; Propargyl-PEG6-Boc; tert-butyl 2-((prop-2-yn-1-yloxy)methyl)-3,6,9,12,15-pentaoxaheptadecanoate
