Abstract
The title compound, C8H5BrN2O6, was synthesized from the nitration of 4-bromo-benzoic acid with fuming nitric acid/sulfuric acid and subsequent esterification by sulfonyl chloride in dry methanol. The NO2 groups are rotated out of conjugation with the aromatic ring, with dihedral angles of 55.6 (4) and 79.5 (3)°.
