Bromoform is a brominated organic solvent, colorless liquid at room temperature, with a high refractive index, very high density, and sweet odor is similar to that of chloroform. It is one of the four haloforms, the others being fluoroform, chloroform and iodoform. Bromoform has the chemical formula CHBr3.
Partial reduction of bromoform yields dibromomethane.
Bromoform is a dense colorless liquid at standard conditions, with a high refractive index, with a sweet odor typical of halocarbons and immiscible with water and polar solvents, but miscible with most non-polar solvents.
Bromoform is sold by chemical suppliers.
Small amounts of bromoform are produced by seaweed.
Bromoform can be prepared by the haloform reaction using a methyl ketone like acetone and sodium hypobromite.

- Separation of minerals by density

Bromoform is harmful and exposure may cause irritation to the respiratory tract, the eyes and the skin, and may cause effects on the central nervous system and liver, resulting in impaired functions. It can be absorbed into the body by inhalation and through the skin.
The International Agency for Research on Cancer (IARC) concluded that bromoform is not classifiable as to human carcinogenicity, however the EPA classifies bromoform as a probable human carcinogen.
In closed amber glass bottles with a suitable cap, in a dark place away from heat and light. Ethanol is sometimes used as stabilizer.
Bromoform should be first diluted, before destroyed with a solution of sodium hydroxide.
