How to detect Methyl bromide
Formula: CH3Br | CAS: 74-83-9
Synonyms: bromomethane, bromomethane, Dowfume, Embafume, Halon 1001, Metafume, monobromomethane, Profume
Methyl bromide is used as a fumigant for soil and foodstuffs, particularly toxic to termites and nematodes. It is used to degrease wool, as a solvent for aniline dyes and fragrances and flavours from flowers and foodstuffs.
