The crystal structure strongly suggests both interhalogen and hydrogen-halogen interactions.

[2] Dibromomethane is prepared commercially from dichloromethane via bromochloromethane: The latter route requires aluminium trichloride as a catalyst.

Dibromomethane is used as a solvent, gauge fluid, and in organic synthesis (often as 1H-NMR internal standard).

[3] It conviently converts polyols (such as catechols) to their methylenedioxy derivatives, and bromomethylenates enolates.

In the atmosphere it will be lost because of reaction with photochemically produced hydroxyl radicals.
