Dicobalt Octacarbonyl
Synonym: Cobalt carbonyl, Cobalt tetracarbonyl dimer, Octacarbonyldicobalt, Cobalt Octacarbonyl
CAS Number 10210-68-1 | MDL Number MFCD00016024
Dicobalt octacarbonyl is used for atomic layer deposition by the semiconductor 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 on specific surfaces, enabling superior film performance in regards to 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 of Dicobalt Octacarbonyl in small and bulk volumes. Glass ampules and bottles or metal ampules and bubblers are available for packaging. For additional information or details about purchasing Dicobalt Octacarbonyl contact us at sales@ereztech.com
