Diethyldicyclopentadiene is used for the synthesis of organometallic compounds. The CVD of carbon and carbon-related compounds are very well developed. This includes, for example, the CVD preparation of carbon nanotubes (CNT), graphene, diamond thin films., as well as various carbon-doped materials (such us C-doped GaAs, AlGaAs, etc.). 

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 Diethyldicyclopentadiene, mixture of isomers contact us at
