title: 6-Chloro-8-methyl-4H-3,1-benzoxazine-2,4(1H)-dione.
abstract: The two mol-ecules in the asymmetric unit of the title compound, C(9)H(6)ClNO(3), are nearly planar, with r.m.s. deviations of 0.034 and 0.037 Å. The crystal structure is stabilized by two weak inter-molecular N-H⋯O inter-actions.
