Chemical compound

Valerophenone, or butyl phenyl ketone, is an aromatic ketone with the formula C6H5C(O)C4H9. It is a colorless liquid that is soluble in organic solvents. It is usually prepared by the acylation of benzene using valeryl chloride.

Selected reactions

Being prochiral, valerophenone undergoes enantioselective hydrogenation to the corresponding alcohol.

Its photochemistry has been studied.

Valerophenone is also an inhibitor of the enzyme carbonyl reductase.
