The title compound, C(15)H(12)ClNO, a substituted chalcone, adopts an E configuration with respect to the C=C bond of the enone unit. The mol-ecule is not planar, as can be seen from the dihedral angle of 28.9 (2)° between the two rings which are twisted from each other. The enone segment of the mol-ecule is not coplanar with the chloro-phenyl ring, making a dihedral angle of 23.4 (3)° with it. The amino group is also not coplanar with the ring to which it is bound, making a dihedral angle of 35 (4)°. In the crystal structure, adjacent mol-ecules are linked by N-H⋯O inter-actions into one-dimensional infinite chains along the c axis, and are further stacked as one-dimensional zigzag chains down the b axis, forming two-dimensional extended networks parallel to the bc plane.
