2H
4Br
2. Although trace amounts occur naturally in the ocean, where it is probably formed by algae and kelp, 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 fumigant.[4] The combustion of 1,2-dibromoethane produces hydrogen bromide gas that is significantly corrosive.[5]
