What is "succinonitrile"

n. (context chemistry English) A nitrile with chemical formula C₂H₄(CN)₂, a colourless waxy solid.

Succinonitrile, also butanedinitrile, is a nitrile, with the formula of CH(CN). 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:

Hydrogenation of succinonitrile yields 1,4-diaminobutane.
