Tungsten hexacarbonyl is easily vaporized and decomposed by the electron beam — providing a convenient source of tungsten atoms. This product is widely used in electron beam-induced deposition processes, it is also used as a precursor to catalysts for alkene metathesis and to desulfurize organosulfur compounds. It is relatively air-stable, and it is sparingly soluble in non-polar organic solvents. W(CO)₆ reactions begin with the displacement of some of its CO ligands. Similar to Mo(CO)₆ in behavior, W(CO)₆ typically forms compounds that are kinetically more robust. The synthesis of this product is reported (see the links below).

Ereztech manufactures and sells this product in small and bulk volumes. Glass ampules, bottles or metal ampules or bubblers are available for packaging. For additional analytical information or details about purchasing Tungsten hexacarbonyl contact us at sales@ereztech.com
