Dicobalt octacarbonyl is used for atomic layer deposition by semiconductors and related industries. Surfaces for such deposition can include metals, metal nitrides, metal silicides, and metal oxides. This product is valued for its ability to be a precursor for the selective deposition of cobalt-containing films onto specific surfaces, enabling superior film performance regarding continuity, uniformity, and low resistance. In organometallic chemistry and organic synthesis Co2(CO)8 is a reagent and catalyst used for hydroformylation: the conversion of alkenes into aldehydes. This product is highly reactive towards alkynes, so it is sometimes used as an alkyne-protecting compound. Synthesis of this product has been reported (see the links below). Ereztech manufactures and sells Dicobalt Octacarbonyl in small and bulk volumes. Glass ampules and bottles or metal ampules and bubblers are available for packaging.
