Molybdenum hexacarbonyl, due to its ability easily vaporized and decomposed by the electron beam, is widely used in electron beam-induced deposition technique. It is used as a reagent in organometallic synthesis because of the displacement of carbonyl ligands by other donor ligands. This product also utilized as a precursor for the manufacture of organomolybdenum dyes and for Molybdenum plating by thermal decomposition. In organic synthesis, its derivatives are employed as catalysts.

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 Molybdenum hexacarbonyl contact us at
