The title compound, C8H8BrNO4S, a halogenated sulfon­amide, was prepared by basic hydrolysis of the methyl ester. In the crystal, mol­ecules form centrosymmetric hydrogen-bonded dimers via the carboxyl groups. These dimers are further linked by N—H⋯O inter­actions involving the carbonyl O and amide H atoms, forming a ribbon-like structure propagating in [010]. These ribbons are further linked via C—H⋯O inter­actions, forming a three-dimensional network.
