CAS RN: 74-90-8

Major Uses

For hydrogen cyanide (USEPA/OPP Pesticide Code: 045801) there are 0 label matches. /SRP: Not registered for current use in the U.S., but approved pesticide uses may change periodically and so federal, state and local authorities must be consulted for currently approved uses./
Reagent in organic synthesis; rodenticide; insect fumigant; chemical warfare agent.
Major end uses include the production of adiponitrile, methyl methacrylate, cyanuric chloride, chelating agents, sodium cyanide, and methionine and its hydroxy analogues.
Estimates of various uses for hydrogen cyanide in the United States are in order of use as follows: acetone cyanohydrin for acrylic plastics; adiponitrile for nylon; sodium cyanide for gold recovery; methionine for animal feed; cyanuric chloride for pesticides and other agricultural products; and chelating agents such as EDTA. Modest quantities of hydrogen cyanide go into a large number of relatively small uses, including manufacture of ferrocyanides, acrylates, lactic acid, pharmaceuticals and specialty chemicals.
In metal polishes, electroplating soln, metallurgical, and photographic processes.
Fumigation of ships, buildings, orchards, and various foods; in electroplating; in mining; in the production of various resin monomers such as acrylates, methacrylates, and hexamethylenediamine; and in the production of nitriles.
HCN was used under tents to control scale and other citrus pests. Its use for this purpose has been discontinued because California red scale developed resistance to gas. /Former use/
Manufacture of acrylonitrile, acrylates, adiponitrile, cyanide salts, dyes, rodenticides, pesticides.
Formerly as a fumigant for furniture restoration, in grain silos and orange groves.
Chemical warfare agent .... primarily tested and used in aerosol form and are considered non-persistent in air. ...Used in World War I by France, by Germany in World War II, and by Iraq against the Kurds in the 1980s.
Hydrogen cyanide, under the name Zyklon B, was used as a genocidal agent by the Germans in World War II. Reports have indicated that during the Iran-Iraq War in the 1980s, hydrogen cyanide gas may have been used along with other chemical agents against the inhabitants of the Kurdish city of Halabja in northern Iraq.
Hydrogen cyanide has been used as the instrument of execution for convicted criminals in some states of the USA primarily because of its rapid effect due to inhalation of high concn.
Hydrogen cyanide is used as a starting material for nylon 66, a hexamethylenediamine-adipic acid polymer
Used to produce cyanuric acid by reacting with sodium hydroxide followed by chlorination. The product polymerizes to cyanuric chloride, a raw material for 2,4,6-s-triazine herbicides.
Used as a raw material for nitriloacids.
Hydrogen cyanide reacts with 3-(methylthio)propionaldehyde to produce 3-(methylthio)propionaldehyde cyanohydrin. This reacts with ammonia to produce 2-aminonitrile, which is hydrolyzed to methionine.
