In the title compound, C13H12Cl2O4S, both C=C double bonds adopt an E conformation. The S atom has a distorted tetrahedral geometry with bond angles ranging from 103.03 (12) to 118.12 (13)°. The ethoxycarbonyl group is disordered over two sets of sites, with site-occupancy factors of 0.739 (11) and 0.261 (11). In the crystal, C-HO interactions link the molecules into chains molecules running parallel to the a axis.
