Malononitrile is a weak cyanocarbon acid with exceptional reactivity. It is used extensively as a reactant or reaction intermediate since the methylene group and either one or both cyano groups can take part in condensation reactions to give a variety of additional products and heterocyclic compounds. This unique reactivity makes malononitrile an important chemical in research and in medical, industrial, and agricultural chemistry. In the late 1940's malononitrile was used experimentally in the treatment of schizophrenia and depression.

In Vivo Use Guide

In the late 1940's malononitrile was used experimentally in the treatment of schizophrenia and depression. ... Patients were given an intravenous infusion of 5% malononitrile for 10-69 min. The total dose during each treatment ranged from 1 to 6 mg/kg. Treatments were given 2-3 times/wk, with at least 1 day intervals. Ten to 20 min after the beginning of the infusion, all patients experienced tachycardia. In addition, redness, nausea, vomiting, headache, shivering, muscle spasms, & numbness were reported with varying frequency.
