In the title carboxyl-ate derivative, C11H5N3O9, the picryl ring forms an angle of 75.79 (7)° with the ester fragment, indicating a near perpendicular disposition. The nitro substituents are variously oriented with respect to the picryl ring [dihedral angles = 3.22 (10), 16.03 (12) and 36.63 (10)°]. In the crystal, mol-ecules form helical chains sustained by C-H⋯O inter-actions along . The furanyl residue is disordered, having two coplanar slightly displaced orientations [major component = 0.730 (9)].
