Succinonitrile, also butanedinitrile, is a nitrile, with the formula of C2H4(CN)2. It is a colorless solid that melts at 57°C, hence its waxy consistency.
Succinonitrile is produced by the addition of hydrogen cyanide to acrylonitrile:
CH2=CHCN + HCN → NCCH2CH2CN
Hydrogenation of succinonitrile yields 1,4-diaminobutane.
