1,1-Dibromoethane is a clear, slightly brown, flammable chemical compound.[3] It is classified as the organobromine compound, and has the chemical formula C2H4Br2[4] and it is a position isomer of 1,2-Dibromoethane. It is commonly seen in the industrial chemistry, where it is used as fuels or fuel additives.[5] Another usage that is seen would be grain and soil fumigant for insect control.[6]


1,1-Dibromoethane is synthesized through addition of hydrogen bromide onto vinyl bromide with absence of peroxide radical.[7]

1,1-Dibromoethane is considered as a mild toxic compound, especially with bromines attached as substituents. Bromines on the ethane are strong oxidizing agents. If absorbed through inhalation, 1,1-dibromoethane could potentially cause neuronal effects, tissue damage, and bromism.[8]
