Abstract: The crystal structure of the title compound, C₁₀H₈BrNO₃, establishes that condensation of 4-bromoaniline with maleic anhydride gives the title compound at room temperature. There are strong intermolecular N-HO hydrogen bonds [NO = 2.814  (3)  Å and 2.817  (3)  Å] linking the molecules into sheets lying parallel to the bc plane. The carboxyl groups adopt an anti-planar conformation and participate in intramolecular O-HO hydrogen bonds [OO = 2.484  (3) and 2.487  (3)  Å]. There are two molecules in the asymmetric unit.
