Description and Uses

Bromodichloromethane is a liquid. Molecularweight=163.8; Specific gravity (H2O:1)=1.98; Boilingpoint=90℃. Odor threshold=about 1675 mg/m3. Solublein water.

As a chemical intermediate for organic synthesis and as a laboratory reagent; formerly used as a solvent and flame retardant. Currently, the major source of bromodichloromethane in the environment is from its formation as a by-product during chlorination of water.
