1,3-Bis[(6-methyl-2-pyridyl)methyl]imidazolium bromide

5-Carbamoyl-2-methyl-1-(2-methyl­benz­yl)pyridinium bromide

In the title mol-ecular salt, C(15)H(17)N(2)O(+)·Br(-), the benzene and pyridinium rings form a dihedral angle of 83.0 (1)°. In the crystal, N-H⋯Br and N-H⋯O hydrogen bonds link the components into chains along [010]. These chains are linked by weak C-H⋯O and C-H⋯Br hydrogen bonds, forming a three-dimensional network.

Methyl bromide under fire.

Methyl Bromide under Fire Methyl bromide is one of the most widely used pesticides in the world, a broad-spectrum fumigant effective in controlling insects, nematodes, fungi, and bacteria. Methyl bromide is also highly toxic to humans. In December 1993, the EPA listed methyl bromide as a stratospheric ozone-depleting substance subject to phase-out. The final rule, issued 1 January 1994, freezes...

Methyl bromide poisoning.

Methyl bromide is a highly volatile liquid which disperses rapidly and readily. As a fumigant it ranks amongst the most efficient because of its extremely effective penetrating power and absence of fire or explosion hazard. It is, unfortunately, highly toxic and poisoning occurs readily in circumstances of careless or inadvertent exposure. Before 1940, only 42 cases of methyl bromide poisoning ...

Fatal methyl bromide poisoning.

Methyl bromide was commonly used in fire extinguishers in aircraft engines and in submarines during the second world war. Now it is widely used as a fumigant insecticide in grain stores.' 2 Mortality after intoxication by methyl bromide vapour may be high,' and is often associated with convulsions, usually resistant to standard anticonvulsant chemotherapy.' s We wish to draw attention to the co...
