Description and Uses

Malonitrile, also known as Malononitrile, is an aliphatic nitrile that can release cyanide through chemical or biological transformation. It was also used decades ago for treating certain forms of mental illness.

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
