Moderately toxic by ingestion, subcutaneous, and intraperitoneal routes. Mildly toxic by inhalation. An eye and mucous membrane irritant. Mutation data reported. Flammable liquid when exposed to heat, sparks, or flame. Can react with oxidizing materials. To fight fire, use water to blanket fire, foam, CO2, water spray or mist, dry chemical. Violent reaction with bromobutane + sodium when heated above 30°C. When heated to decomposition it emits toxic fumes of Br−. See also BROMIDES.

DOT Classification: 3; Label: Flammable Liquid
Specification
Bromobenzene (CAS NO.108-86-1) is also named as AI3-09059 ; Benzene, bromo- ; CCRIS 5887 ; HSDB 47 ; Monobromobenzene ; NCI-C55492 ; NSC 6529 ; Phenyl bromide . Bromobenzene (CAS NO.108-86-1) is colourless liquid with a pungent odor. It is insoluble in water, soluble in benzene, alcohol, ether, chlorobenzene and other organic solvents. Vapors are heavier than air. It is flammable. Bromobenzene may be sensitive to light. It may react with oxidizing agents. Contact with liquid causes irritation of eyes and mild irritation of skin. Ingestion causes mild irritation of mouth and stomach. It may produce irritating hydrogen bromide and other gases in fire.
