1, 2-Dibromoethane dibromide

DibrOmoethane dibromide. Also has a very high Constant, but sometimes causes association of the solute. It usually gh es excellent consistent results. 

Bromine is used in the manufacture of many important organic compounds including 1,2-dibromoethane (ethylene dibromide), added to petrol to prevent lead deposition which occurs by decomposition of the anti-knock —lead tetraethyl bromomethane (methyl bromide), a fumigating agent, and several compounds used to reduce flammability of polyester plastics and epoxide resins. Silver(I) bromide is used extensively in the photographic industry...

There has been much interest recently in the reaction of a, o)-di-halogenoalkanes. 1,2-Dibromoethane reacts with phthalazine to give ethane 1,2-bis-phthalazinium dibromide (1), none of the mono salt being formed directly, but the same dibromo compound and a, a -dipyridyl give the cyclic compound 2. ... 

Vicinal (Section 8.2) A term used to refer to a 1,2-disubstitution pattern. For example, 1,2-dibromoethane is a vicinal dibromide.

This Statement was prepared to give you information about 1, 2-dibromoethane (ethylene dibromide, EDB) and to emphasize the human health effects that may result from exposure to it. The Environmental Protection Agency (EPA) has identified 1,177 sites on its National Priorities List (NPL). 1,2-Dibromoethane has been found at 9 of these sites. However, we do not know how many of the 1,177 NPL sites have been evaluated for 1,2-dibromo-ethane. As EPA evaluates more sites, the number of sites at which 1,2-dibromoethane is found may change. The information is important to you because 1,2-dibromoethane may cause harmful health effects and because these sites are potential or actual sources of human exposure to 1,2-dibromoethane. 

Disulfiram is the generic name for Antabuse, a drug used in the treatment of chronic alcoholism. Disulfiram potentiates the toxic and carcinogenic effects of 1,2-dibromoethane in experimental animals. Presumably, this occurs by blocking conversion of the aldehyde metabolite as with acetaldehyde from ethanol. There is no evidence that similar effects occur in humans. Based on animal data, however, Ayerst Laboratories, producers of Antabuse (disulfiram), recommended the following in the package insert "Patients taking Antabuse tablets should not be exposed to ethylene dibromide or its vapors" (PDR 1991).
