The asymmetric unit of the title compound, C19H19ClO4, contains two independent mol­ecules. The dihedral angles between the benzene rings are 63.41 (8) and 61.41 (9)°. Adjacent mol­ecules of different types are inter­connected in pairs through π–π inter­actions between their central benzene rings [centroid–centroid separation = 3.801 (2) Å, inter­planar spacing = 3.605 (2) Å, centroid shift = 1.204 (2) Å]. Finally, C—H⋯O hydrogen bonds link these dimers into bilayers parallel to (100).
