dibromoethane

Dibromoethane refers to any of three isomers of the chemical compound C2H4Br2, where two bromine atoms are bonded to an ethane backbone. The most common isomer is 1,2-dibromoethane. It is a colorless liquid with a sweet odor. It is denser than water and has low solubility in it.

1,2-Dibromoethane was historically used as a fumigant for soil and as an additive in leaded gasoline to prevent lead buildup in engines. However, due to its toxicity and environmental concerns, its use has been largely phased out in many countries. It is classified as a probable human carcinogen. Exposure can occur through inhalation, skin contact, or ingestion. Symptoms of exposure can include respiratory irritation, nausea, vomiting, and damage to the liver and kidneys.

1,2-Dibromoethane can be synthesized by the direct bromination of ethene. This reaction is a classic example of electrophilic addition. The compound is also an intermediate in the synthesis of other organic chemicals. Research into its properties and potential uses continues, though its primary applications are now limited due to safety regulations.
