Overview

1,2-dibromoethane (CAS 106-93-4) is a halogenated hydrocarbon with significant industrial applications and notable toxicological properties. This colorless liquid compound, also known by its molecular formula C2H4Br2, represents one of the most important dibromoalkanes in industrial chemistry. With a molecular weight of 187.86 g/mol, 1,2-dibromoethane exhibits the characteristic properties of organobromine compounds, including high density and relatively low volatility compared to lighter halogenated hydrocarbons. The compound's structure features two bromine atoms attached to adjacent carbon atoms, creating a vicinal dibromide configuration that imparts unique reactivity patterns. The substance carries significant safety considerations, classified under GHS pictograms GHS08, GHS06, and GHS09, reflecting its carcinogenic potential (Category 1B), acute toxicity, and environmental hazards. As an ADR Class 6.1 material, 1,2-dibromoethane requires specialized handling protocols and appropriate personal protective equipment during transport and use. The "Danger" signal word emphasizes the need for comprehensive safety measures, including adequate ventilation systems and exposure monitoring in workplace environments. Industrial applications of 1,2-dibromoethane primarily include its use as an intermediate in organic synthesis, particularly in the production of vinyl bromide and other brominated compounds. The chemical industry also employs it in specialized solvent applications and as a fumigant, though regulatory restrictions have limited certain historical uses. Unlike simpler compounds such as dichlorocadmium, 1,2-dibromoethane's dual bromine functionality enables complex chemical transformations essential for pharmaceutical and agrochemical manufacturing. OYSI maintains reliable supply chains for 1,2-dibromoethane, ensuring consistent availability for European industrial customers requiring this specialized chemical intermediate.

Frequently Asked Questions

What is 1,2-dibromoethane?

1,2-dibromoethane is an organohalogen compound with the chemical formula C2H4Br2 and CAS number 106-93-4. This colorless liquid consists of two carbon atoms each bonded to hydrogen and bromine atoms. With a molecular weight of 187.86 g/mol, it belongs to the dibromoalkane family and is classified as a highly hazardous substance due to its carcinogenic properties and acute toxicity.

What are the physicochemical properties of 1,2-dibromoethane?

1,2-dibromoethane is a colorless, dense liquid with a sweet chloroform-like odor at room temperature. It has a boiling point of 131-132°C and a melting point of 9.8°C. The compound is slightly soluble in water but readily dissolves in organic solvents like ethanol, ether, and acetone. Its density is approximately 2.18 g/cm³, making it significantly denser than water.

What is 1,2-dibromoethane used for?

1,2-dibromoethane is primarily used as an intermediate in chemical synthesis and as a fumigant. Historically, it was extensively used as a lead scavenger in leaded gasoline and as a soil fumigant for pest control. Currently, its applications are heavily restricted due to health concerns, but it may still be used in specialized chemical manufacturing processes and research applications under strict safety protocols.

How to handle 1,2-dibromoethane safely?

1,2-dibromoethane requires extreme caution during handling due to its carcinogenic and toxic properties.
