Reactivity & Insolubility: When the carbon halogenide mixes with potassium or other alloys, it is sensitive to the shock and it may explode because of the strenuous movement or light irradiation.
Decomposability: Produces bromine hydride-containing toxic gas when carries on the thermal decomposition.
Main Use: As the pesticide intermediate, the dibromomethane is the main raw material for synthesizing new type highly effective and broad-spectrum bactericide, it also is the raw material of large tonnage acaricide. Dibromomethane is a kind of good fire retardant, when add it into the polymer, it can effectively reduces the combustion heat when the plastic's burning.
