The Montreal Protocol stipulates that bromomethane use be phased out. Bromomethane is also a precursor in the manufacture of pharmaceuticals such as neostigmine bromide, pancuronium bromide, propantheline bromide], pyridostigmine bromide, atropine derivatives, clidinium bromide, clobazam, demecarium bromide, glycopyrrolate, and vecuronium bromide.
The most pervasive is the naturally produced bromomethane. One prominent application of synthetic organobromine compounds is the use of polybrominated diphenyl ethers as fire-retardants, and in fact fire-retardant manufacture is currently the major industrial use of the element bromine.
Bromomethane; Bromoiodomethane; n-Propyl bromide; ... Uses. In organic synthesis, EtBr is the synthetic equivalent of the ethyl carbocation (Et +) synthon. [5]
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.
Tetrafluoroethane (a haloalkane) is a colorless liquid that boils well below room temperature (as seen here) and can be extracted from common canned air canisters by simply inverting them during use. The haloalkanes (also known as halogenoalkanes or alkyl halides) are alkanes containing one or more halogen substituents. [1]
Poisonous bromomethane was widely used as pesticide to fumigate soil and to fumigate housing, by the tenting method. Ethylene bromide was similarly used. [67] These volatile organobromine compounds are all now regulated as ozone depletion agents.

The four common [a] members are fluoromethane, chloromethane, bromomethane and iodomethane. Historical name for this group is methyl halides; it's still widely used. The compounds of this class are often described as CH 3 X or MeX (X - any halogen, Me - methyl group).
