74-95-3 Usage

General Description

A colorless liquid with a pleasant odor. Insoluble in water and denser than water. May be toxic by ingestion. Used as a solvent and as a motor fuel.

Air & Water Reactions

Insoluble in water.

Reactivity Profile

Halogenated aliphatic compounds, such as Dibromomethane, are moderately or very reactive. Reactivity generally decreases with increased degree of substitution of halogen for hydrogen atoms. Low molecular weight haloalkanes are highly flammable and can react with some metals to form dangerous products. Materials in this group are incompatible with strong oxidizing and reducing agents. Also, they are incompatible with many amines, nitrides, azo/diazo compounds, alkali metals (potassium), and epoxides.

Definition

ChEBI: A member of the class of bromomethanes that is methane substituted by two bromo groups. It is produced by marine algae.

Health Hazard

INHALATION: Anesthetic effects, nausea and drunkenness. CONTACT WITH SKIN AND EYES: Skin irritation of eyes and nose.

Fire Hazard

Special Hazards of Combustion Products: Dissociation products generated in a fire may be irritating or toxic.
