The chemical properties of malononitrile are determined by the nucleophilicity of the malononitrile anion, formed by deprotonation with relatively weak bases and by the two electrophilic cyano groups. | 【Usage】
Malononitrile is an important building block for the syntheses of pharmaceuticals (e.g. triamterene, adenine and methotrexate), thiamin (vitamin B1), pesticides dyestuffs for color photography and synthetic fibers (e.g. vinylidene cyanide). Product Data Sheet | 【Usage】

| Hazard Information | Back Directory | 【General Description】
A white-colored crystalline solid. Denser than water and soluble in water. Toxic by ingestion and may severely irritate skin and eyes. May polymerize violently if exposed to temperatures above 266°F. Used to make other chemicals. | 【Reactivity Profile】
MALONONITRILE(109-77-3) is a white, low-melting powder (m. p. 30.5° C), toxic, combustible. Violent polymerization on contact with strong bases (sodium hydroxide, potassium hydroxide) or when heated above 130° C. When stored at 70-80° C for 2 months, spontaneous explosion (decomposition) occurred [Bretherick, 5th ed., 1995, p. 394]. | 【Air & Water Reactions】
Soluble in water. | 【Health Hazard】
Metabolized by body to cyanide and thiocyanate; effects of inhalation of toxic fumes will be related to cyanide. Causes brain and heart damage related to lack of cellular oxygen. It is classified as extremely toxic. Probable oral lethal dose for humans is 5-50 mg/kg, or between 7 drops and 1 teaspoonful, for a 70 kg (150 lb.) person. | 【Fire Hazard】
When heated to decomposition, malononitrile emits highly toxic fumes (cyanide). May polymerize violently on prolonged heating. Avoid heat. Hazardous polymerization may occur, at prolonged heating at 266F or contact with strong bases at lower temperatures. |
