Hazard InformationBack Directory
[General Description]

Colorless liquid and an odor of onions. Used as an agricultural insecticide, a fumigant and as a research chemical. No evidence of commercial production in the U.S.
[Reactivity Profile]

METHYL THIOCYANATE(556-64-9) is a moderately toxic liquid, flammable. Violent, possibly explosive oxidation reaction when mixed with chlorates, nitrates, nitric acid, organic or inorganic peroxides, perchlorates. On contact with mineral acids or acid fumes deadly toxic hydrogen cyanide gas is produced. When heated to decomposition or on contact with mineral acids METHYL THIOCYANATE(556-64-9) emits highly toxic fumes of nitriles, oxides of sulfur and nitrogen [Lewis, 3rd ed., 1993, p. 879, 1234].
[Air & Water Reactions]

Very slightly soluble in water [Merck].
[Health Hazard]

This material is highly toxic if ingested. It is a rapidly acting poison.
[Potential Exposure]

It is used as an agricultural insecticide; a fumigant; and as a research chemical. No evidence of commercial production in the United States.
[Fire Hazard]

When heated to decomposition, METHYL THIOCYANATE emits very toxic fumes of oxides of nitrogen and sulfur. (Non-Specific--Thiocyanates) Incompatible with nitric acid. Violent reactions have occurred when mixed with chlorates, nitrates, nitric acid, organic peroxides, peroxides, potassium chlorate, and sodium chlorate. This material is volatile.
[First aid]

If this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 15 minutes, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts the skin, remove contaminated clothing and wash immediately with soap and water. Seek medical attention immediately. If this chemical has been inhaled, remove from exposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if heart action has stopped. Transfer promptly to a medical facility. When this chemical has been swallowed, get medical attention. Give large quantities of water and induce vomiting. Do not make an unconscious person vomit. Note: Because cyanide is probably largely responsible for poisonings, antidotal measures against cyanide should be instituted promptly. Use amyl nitrate capsules if symptoms develop. All area employees should be trained regularly in emergency measures for cyanide poisoning and in CPR. A cyanide antidote kit should be kept in the immediate work area and must be rapidly available. Kit ingredients should be replaced every 12 years to ensure freshness. Persons trained in the use of this kit; oxygen use, and CPR must be quickly available.
