Dibromomethane, also known as dibromodifluoromethane or R-30B, is a colorless liquid with a sweet odor. It is a halogenated hydrocarbon with the chemical formula CH2Br2. It is an organobromine compound and a difluoromethane derivative. Dibromomethane is sparingly soluble in water but soluble in many organic solvents, including ethanol and diethyl ether.

Dibromomethane is primarily used as a solvent for resins, waxes, and fats. It has also been employed as a fumigant and a refrigerant. Its applications have declined due to environmental concerns and the availability of less toxic alternatives. Dibromomethane is considered a potential ozone-depleting substance, though its impact is less significant than that of chlorofluorocarbons.

In laboratory settings, dibromomethane can be synthesized by the reaction of methane with bromine under UV light. It can also be prepared by the reaction of dichloromethane with hydrobromic acid in the presence of a catalyst.

Dibromomethane is a toxic compound and can cause irritation to the skin, eyes, and respiratory tract. Inhalation of high concentrations can lead to central nervous system depression, dizziness, and nausea. Prolonged exposure may result in liver and kidney damage. Due to its toxicity, it should be handled with appropriate safety precautions, including good ventilation and personal protective equipment.
