Methyl thiocyanate Usage And Synthesis
  • Chemical PropertiesCLEAR COLOURLESS TO LIGHT YELLOW LIQUID
  • Chemical PropertiesMethyl thiocyanate is a colorless liquid. Onion-like odor
  • DefinitionChEBI: Methyl thiocyanate is a member of the class of thiocyanates, being the methyl ester of thiocyanic acid.
  • General DescriptionColorless 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.
  • Air & Water ReactionsVery slightly soluble in water [Merck].
  • Reactivity ProfileMethyl 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].
  • Health HazardMethyl thiocyanate is highly toxic if ingested. It is a rapidly acting poison.
  • Fire HazardWhen 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.
  • Safety ProfilePoison by ingestion, intravenous, and subcutaneous routes. When heated to decomposition it emits very toxic fumes of NOx and SOx.
  • Potential ExposureIt is used as an agricultural insecticide; a fumigant; and as a research chemical. No evidence of commercial production in the United States.
  • ShippingUN2929 Toxic liquids, flammable, organic, n.o.s., Hazard class: 6.1; Labels: 6.1-Poison Inhalation Hazard, 3-Flammable liquid, Technical Name Required. UN1992 Flammable liquids, toxic, n.o.s., Hazard Class: 3; Labels: 3-Flammable liquid, 6.1-Poisonous materials, Technical Name Required.
  • IncompatibilitiesIncompatible with nitric acid. Violent reactions have occurred when mixed with chlorates, nitrates, nitric acid; peroxides, potassium chlorate; and sodium chlorate.
