General description
Bromomethane solution (methyl bromide) is the most effective soil fumigant for killing plant pests, its use is being phased out because its emissions from soil can lead to stratospheric ozone depletion. The bimolecular nucleophilic substitution (SN2) reaction of methyl bromide and OH- in aqueous solution has been investigated using a multilayered-representation quantum mechanical and molecular mechanics methodology.
Packaging
Supplied in a Sure/Pac™ cylinder and has a 1/4-turn bronze ball valve with a female 1/4" NPT outlet thread (Z122661) installed. Before using the cylinder, ensure that the valve is closed, then remove carbon steel plug that seals the outlet valve.
Compatible with the following:

Despite generally being considered the most effective soil fumigant, methyl bromide (MeBr) use is being phased out because its emissions from soil can lead to stratospheric ozone depletion. However, a large amount is still currently used due to Critical Use

The bimolecular nucleophilic substitution (S(N)2) reaction of CH(3)Br and OH(-) in aqueous solution was investigated using a multilayered-representation quantum mechanical and molecular mechanics methodology. Reactant complex, transition state, and product complex are identified and characterized in aqueous solution. The potentials

Methyl bromide is a genotoxic soil fumigant with high acute toxicity, but unknown human carcinogenicity. Although many countries have reduced methyl bromide use because of its ozone depleting properties, some uses remain in the United States and other countries, warranting
