Hexynoic acid STP ester is a water-soluble reagent with a terminal propargyl group and a STP ester group. The STP esters are excellent alternatives of conventional N-hydroxysuccinimide (NHS) esters for coupling reaction in aqueous environments. The propargyl group reacts with azide-bearing compounds or biomolecules via copper catalyzed azide-alkyne Click Chemistry to yield a stable triazole linkage. Reagent grade, for research purpose.
