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. ^[1]

Selected reactions

Being prochiral, valerophenone undergoes enantioselective hydrogenation to the corresponding alcohol. ^[2]

Its photochemistry has been studied. ^{[3] [4]}

Valerophenone is also an inhibitor of the enzyme carbonyl reductase. ^[5]
