Butyronitrile

Butyronitrile or butanenitrile or propyl cyanide, is a nitrile with the formula C3H7CN. This colorless liquid is miscible with most polar organic solvents.

Uses
Butyronitrile is mainly used as a precursor to the poultry drug amprolium.

It also has recognized use in the synthesis of Etifelmine.

Synthesis
Butyronitrile is prepared industrially by the ammoxidation of n-butanol:
 * C3H7CH2OH +  NH3  +  O2   →   C3H7CN  +  3 H2O

Occurrence in space
Butyronitrile has been detected in the Large Molecule Heimat in Sagittarius B2 cloud along with other complex organic molecules.
