Hydrogen Cyanide (HCN)

Hydrogen Cyanide (HCN)

Hydrogen cyanide (HCN) – also called hydrocyanic acid or formonitrile – is a chemical compound that can be found in either liquid or gaseous form. Widely used as an insectricide, it is also applied for fumigation applications in the chemical industry. It can be accidentally produced during chemical reactions between cyanide and an acid, or trough fire and nitriles combustion.
