Bromobenzyl cyanide (BBC), also known as 2-Bromo-1-phenylacetonitrile, is a chemical compound that has been used historically as a tear gas agent. It is a member of the cyanide family and is known for its potent lachrymatory effects.

Chemical Properties[edit | edit source]

Bromobenzyl cyanide is an organic compound with the chemical formula C8H6BrN. It consists of a benzene ring substituted with a bromine atom and a cyanide group. The presence of the bromine atom makes it a halogenated compound, which contributes to its reactivity and toxicity.

Synthesis[edit | edit source]

Bromobenzyl cyanide can be synthesized through the bromination of benzyl cyanide. The reaction typically involves the use of bromine in the presence of a catalyst or under specific conditions to ensure the selective substitution of the hydrogen atom on the benzyl group with a bromine atom.

Uses[edit | edit source]

Historically, bromobenzyl cyanide was used as a riot control agent due to its ability to cause irritation to the eyes, skin, and respiratory system. It was employed in various military and law enforcement applications to disperse crowds and incapacitate individuals temporarily.

Health Effects[edit | edit source]

Exposure to bromobenzyl cyanide can result in severe irritation of the eyes, skin, and respiratory tract. Symptoms of exposure include tearing, burning sensation, coughing, and difficulty breathing. Prolonged or high-level exposure can lead to more serious health effects, including chemical burns and respiratory distress.

Safety and Handling[edit | edit source]

Due to its toxic nature, bromobenzyl cyanide must be handled with extreme care. Appropriate personal protective equipment (PPE) such as gloves, goggles, and respirators should be used when handling the compound. In case of exposure, affected individuals should seek immediate medical attention.

Regulation[edit | edit source]

The use of bromobenzyl cyanide as a chemical weapon is restricted under various international treaties, including the Chemical Weapons Convention. Its production and use are subject to strict regulatory controls to prevent misuse and ensure public safety.
