The asymmetric unit of the title compound, C11H11ClN2, contains two almost-planar independent molecules: the isoindole and dimethylaminomethylene mean planes in the two molecules form dihedral angles of 5.45 (8) and 1.34 (8)°. The crystal packing exhibits no short intermolecular contacts, except for a relatively short ClCl distance of 3.4907 (7) Å.
