Bromoform was discovered in 1832 by Löwig who distilled a mixture of bromal and potassium hydroxide, as analogous to preparation of chloroform from chloral. [5]Bromoform can be prepared by the haloform reaction using acetone and sodium hypobromite, by the electrolysis of potassium bromide in ethanol, or by treating chloroform with aluminium bromide.
Representative agents include bromoform and dibromodimethylhydantoin ("DBDMH"). [7] Some herbicides, such as bromoxynil , contain also bromine moieties. Like other halogenated pesticides , bromoxynil is subject to reductive dehalogenation under anaerobic conditions, and can be debrominated by organisms originally isolated for their ability to ...
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.
The culprit appears to be trihalomethanes (THMs), which are made up of four compounds — chloroform, bromodichloromethane, dibromochloromethane and bromoform. THMs are found in nearly all public ...

Most of the haloforms — specifically, chloroform (CHCl 3), bromoform (CHBr 3), and iodoform (CHI 3) — are easy to prepare through the haloform reaction, although this method does not lend itself to bulk syntheses. (Fluoroform (CHF 3) cannot be prepared in this manner.)
Bromodichloromethane is a trihalomethane with formula C H Br Cl 2.It is a colorless, nonflammable liquid which will dissolve in water, or evaporate in air. [1] Most of the chemical is produced through the chlorine disinfection process, [1] and as a result it can occur in municipally-treated drinking water. [2]
