Metabolite Identification

Common Name

1,2-Dibromoethane

Description

1,2-Dibromoethane, also known as ethylene dibromide or DBE, belongs to the class of organic compounds known as organobromides. Organobromides are compounds containing a chemical bond between a carbon atom and a bromine atom. 1,2-Dibromoethane is possibly neutral. Trace amounts of 1,2-dibromoethane occur naturally in the ocean, where it is formed probably by algae and kelp. 1,2-Dibromoethane is formally rated as a probable carcinogen (by IARC 2A) and is also a potentially toxic compound. Breathing high levels may cause depression and collapse. 1,2-Dibromoethane is rapidly absorbed by ingestion, inhalation, and dermal routes, then distributed mainly to the kidneys, liver, and spleen. It can be metabolized by either the cytochrome P-450 system or the glutathione S-transferase system. These metabolites may be further broken down and excreted in the urine. The metabolite 2-bromoacetaldehyde produces liver damage by binding to cellular proteins. Long term exposure can result in liver, kidney, and reproductive system damage. 1,2-Dibromoethane is also known to have adverse effects on the brain. S-(2-bromoethyl)glutathione, another metabolite, exerts genotoxic and carcinogenic effects by binding to DNA.
