open-in-new
<p>1,2-Dibromoethane, also known as ethylene dibromide (EDB), is an <a href="/facts/Organobromine_compound/7v9NP0Ak">organobromine compound</a> with the <a href="/facts/Chemical_formula/hghUtthl">chemical formula</a> C2H4Br2. Although trace amounts occur naturally in the <a href="/facts/Ocean/8W8lYgjD">ocean</a>, where it is probably formed by <a href="/facts/Algae/U1ftVKU3">algae</a> and <a href="/facts/Kelp/XGohrJEJ">kelp</a>, substantial amounts are produced industrially. It is a dense colorless liquid with a faint, sweet odor, detectable at 10 ppm. It is a widely used and sometimes-controversial <a href="/facts/Fumigant/QGCodNPb">fumigant</a>. The combustion of 1,2-dibromoethane produces <a href="/facts/Hydrogen_bromide/rUw1duLA">hydrogen bromide</a> gas that is significantly corrosive. </p>
