Succinonitrile, also butanedinitrile, is a nitrile, with the formula of C2H4(CN)2. It is a colorless solid that melts at 58[3] °C, hence its waxy consistency.

Succinonitrile is produced by the addition of hydrogen cyanide to acrylonitrile:[4]

CH2=CHCN + HCN → NCCH2CH2CN

Hydrogenation of succinonitrile yields putrescine (1,4-diaminobutane).
