CYANOGEN BROMIDE Consensus Reports

Cyanide and its compounds are on the Community Right-To-Know List. EPA Extremely Hazardous Substances List. Reported in EPA TSCA Inventory.

CYANOGEN BROMIDE Safety Profile

A human and experimental poison by inhalation. Corrosive. When heated to decomposition it emits very toxic fumes of CN⁻ and Br⁻. Possibly unstable. See also other cyanogen entries; CYANIDE; and BROMIDES.

CYANOGEN BROMIDE Standards and Recommendations

DOT Classification: 6.1; Label: Poison, Corrosive

CYANOGEN BROMIDE Specification

Cyanogen bromide is a colorless to white crystalline solid with a penetrating odor. Cyanogen bromide is slightly soluble in water. Cyanogen bromide is gradually decomposed by water and very rapidly by acids to give off hydrogen bromide, a flammable and poisonous gas. Contamination with many materials can cause rapid decomposition of the material. Cyanogen bromide is toxic by inhalation of its vapors or by the hydrogen cyanide from decomposition or by ingestion. Toxic oxides of nitrogen are produced in fire involving Cyanogen bromide. Cyanogen bromide is used in gold extraction, to make other chemicals, and as a fumigant.
