In the title compound, C13H10ClN3O3, prepared by the reaction of 1-chloro-3-isocyanatobenzene with 4-nitrobenzenamine, the two substituent benzene rings are roughly coplanar [inter-ring dihedral angle = 8.70 (7)°]. In the crystal, molecules make cyclic intermolecular associations through two urea–nitro N—H...O hydrogen bonds, forming a chain structure [give chain direction] in which there are also weak intermolecular C—H...Cl interactions. The urea O atom has only intramolecular aromatic ring C—H...O associations.
