The title compound, C8H13Br2NO3, crystallizes as a non-merohedral twin with twin law -0.6 0 0.4/0 - 1 0 /1.6 0 0.6, and the structure has a refined twin domain ratio of 0.546 (5). The structure shows a compact conformation, with the ester unit roughly coplanar with a mean plane fitted through the non-H atoms of the pyrrolidine ring [dihedral angle = 8.23 (9)°]. In the crystal, inversion dimers linked by pairs of O-HO hydrogen bonds generate an R22(12) motif.
