Hydrogen cyanide properties
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 insecticide, 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 through fire and nitriles combustion.

Hydrogen cyanide effects on health
With variant color from colorless to pale blue, hydrogen cyanide (HCN) is easily detectable through its bitter almond smell. This highly toxic gas (T+) features many harmful or lethal properties. With explosive limits between 5.6 and 40%, this chemical compound is extremely flammable (F+).
