Tri-(Propargyl-PEG2-ethoxymethyl)-methane-amido-PEG3-carboxylate

Propargyl-PEG3-bromide comprises a propargyl group and a bromide group. The propargyl group reacts with azide-bearing compounds or biomolecules in Click Chemistry to yield a stable triazole linkage; copper will be needed as a catalyst. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
