5-Chloro-1-phenylpentan-1-one

In the title compound, C11H13ClO, which is used as a starting material for the synthesis of some materials with possible medical applications, the molecular skeleton is slightly curved, with the dihedral angle of 4.7 (1)° between the mean planes of the chlorobutane and benzaldehyde fragments. In the crystal, weak C—H...O hydrogen bonds link the molecules into chains running along the [201] direction, and weak C—H...π interactions link these chains into layers parallel to the ac plane.
