Bromoform is known as an inhibitor of methanogenesis and is a common component of seaweed. Following research by CSIRO and its spin-off FutureFeed , several companies are now growing seaweed, in particular from the genus Asparagopsis , to use as a feed additive for livestock to reduce methane emissions from ruminants .
The EPA limits the total concentration of the four chief constituents (chloroform, bromoform, bromodichloromethane, and dibromochloromethane), referred to as total trihalomethanes (TTHM), to 80 parts per billion in treated water. [6] Traces of chloroform are produced in swimming pools. [7] [8] [9] [10]
In chemistry, the haloform reaction (also referred to as the Lieben haloform reaction) is a chemical reaction in which a haloform (CHX 3, where X is a halogen) is produced by the exhaustive halogenation of an acetyl group (R−C(=O)CH 3, where R can be either a hydrogen atom, an alkyl or an aryl group), in the presence of a base.
Bromoform, produced by several algae, is a known toxin, though the small amounts present in edible algae do not appear to pose human harm. [12] Some of these organobromine compounds are employed in a form of interspecies "chemical warfare".
The classical heavy liquids like 1,1,2,2-tetrabromoethane (Muthmanns solution), potassium tetraiodomercurate(II) (Thoulets solution), bromoform or diiodomethane which are used in mineralogy are very toxic.
One of the most important uses of the Sandmeyer reaction is the formation of aryl halides. The solvent of choice for the synthesis of iodoarenes is diiodomethane, [17] [18] while for the synthesis of bromoarenes, bromoform is used. For the synthesis of chloroarenes, chloroform is the solvent of choice. [19]

In the original reaction, the organochromium species is generated from iodoform or bromoform and an excess of chromium(II) chloride and the product is a vinyl halide. One main advantage of this reaction is the E-configuration of the double bond that is formed.
