Bromoform is an organic compound with the chemical formula CHBr₃. It is a colorless liquid at room temperature, with a high refractive index and a very high density. Its sweet odor is similar to that of chloroform. It is one of the four haloforms, the others being fluoroform, chloroform, and iodoform. It is a brominated organic solvent. Currently its main use is as a laboratory reagent. It is very slightly soluble in water (one part bromoform in 800 parts water) and is miscible with alcohol, benzene, chloroform, ether, petroleum ether, acetone and oils.
