Quick Summary

Cyanogen is a chemical compound that exists in two forms: a monovalent group (-CN) found in cyanides, and a colorless, flammable, and poisonous gas with the formula (CN)₂. Cyanogen halides are related compounds that are volatile, reactive, tear-producing, and highly poisonous. These include cyanogen fluoride, cyanogen chloride, cyanogen bromide, and cyanogen iodide. Cyanogen bromide, for example, is a crystalline compound used in organic synthesis and as a fumigant. Hydrogen cyanide, also known as hydrocyanic acid, is highly toxic because it interferes with cellular oxidation processes.1234
