Succinonitrile or butanedinitrile, is an organic chemical compound, a nitrile. It has the formula NCCH2CH2CN or C4H4N2.
Hydrogenation of succinonitrile yields putrescine.
Succinonitrile is a waxy colorless solid, that slowly turns brownish in air. It is soluble in water and alcohols.
Butanedinitrile is sold by chemical suppliers.
- CH2=CHCN + HCN → NCCH2CH2CN
- Synthesis of putrescine
Succinonitrile is expected to be toxic, as it's metabolized to free cyanide which is very toxic. It can be absorbed via ingestion, inhalation and skin/eye contact.
In closed bottles, away from corrosive reagents.
Should be carefully mixed with bleach. Alternatively it can be dissolved in a flammable solvent and burned in an incinerator.
