Used as a catalyst in organic synthesis, particularly in alkyne metathesis reactions, enabling the rearrangement of carbon-carbon triple bonds. Its high reactivity and selectivity make it valuable in constructing complex molecular frameworks found in pharmaceuticals and advanced materials. The compound is also studied for potential use in homogeneous catalysis where tungsten-based complexes offer unique electronic properties. Due to its sensitivity, it is typically handled under inert conditions to maintain catalytic activity.
