  "abstract": "The structure of the title compound, C10H13ClO5, was obtained by anhydride ring opening of norcantharidin with chloro-ethanol and pyridine as base. The title compound has triclinic (P1) symmetry, with individual mol-ecules connected via their carb-oxy-lic acid groups into centrosymmetric dimers. Additional C-H⋯O inter-actions connect these dimers into slabs parallel to the ab plane (001). Steric crowding between the carb-oxy-lic acid and ester moieties leads to a strained C-C-C angle involving the ester carbon atom.",
