1,2-Dibromoethylene (DBE) is a chemical substance that is used as a solvent and an intermediate in the production of other chemicals. It is also used for the manufacture of dyes, pharmaceuticals, and pesticides. DBE is classified as a mutagenic carcinogen and can cause cancer in humans. The degradability of DBE depends on its location. In water it undergoes degradation by hydrolysis to form dichloroacetic acid (DCAA). It also undergoes photolysis to form hydrochloric acid (HCl) and bromine atoms. In air it undergoes degradation by oxidation to form chlorine atoms. These chlorine atoms can react with ozone in the atmosphere to form chlorate ions which are highly reactive with metal surfaces such as iron or aluminium. This reaction produces hydrogen chloride gas, which can lead to corrosion of metal structures including bridges or buildings. The structural formula for DBE is CHClBrO.
