Butyronitrile or butanenitrile or propyl cyanide, is a nitrile with the formula C3H7CN. This colorless liquid is miscible with most polar organic solvents.
Butyronitrile is mainly used as a precursor to the poultry drug amprolium.
It also has recognized use in the synthesis of Etifelmine.
Butyronitrile is prepared industrially by the ammoxidation of n-butanol:
Butyronitrile has been detected in the Large Molecule Heimat in Sagittarius B2 cloud along with other complex organic molecules.
