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.
Реакции воздуха и воды
Very slightly soluble in water [Merck].
Профиль реактивности
Methyl thiocyanate 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 emits highly toxic fumes of nitriles, oxides of sulfur and nitrogen [Lewis, 3rd ed., 1993, p. 879, 1234].
Угроза здоровью
Methyl thiocyanate is highly toxic if ingested. It is a rapidly acting poison.
Пожароопасность
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. Methyl thiocyanate is volatile.
Профиль безопасности
Poison by ingestion,
intravenous, and subcutaneous routes.
When heated to decomposition it emits very
toxic fumes of NOx and SOx.
Возможный контакт
It is used as an agricultural insecticide; a fumigant; and as a research chemical. No evidence
of commercial production in the United States.
