Dibromomethane #CAS74-95-3
Dibromomethane is a member of the class of bromomethanes that is methane substituted by two bromo groups. It is produced by marine algae. It has a role as a marine metabolite and an algal metabolite. It is a member of bromomethanes and a bromohydrocarbon.Dibromomethane is a colorless liquid with a sweet, pleasant odor.
A colorless liquid with a pleasant odor. Insoluble in water and denser than water. May be toxic by ingestion. Used as a solvent and as a motor fuel.
Application of Dibromomethane
Organic synthesis, solvent.
Dibromomethane is used as solvent in organic synthesis. It acts as an intermediate in the manufacture of specialty chemicals, agrochemicals and pharmaceuticals. It is useful as extractant and utilized for the determination of 5-nitroimidazoles (5-NDZ) in environmental waters. It is involved in the convertion of catechols to their methylenedioxy derivatives.
