title: 3-(2-Hydr-oxy-5-methyl-anilino)isobenzo-furan-1(3H)-one.
abstract: In the mol-ecule of the title compound, C(15)H(13)NO(3), the phthalide ring system is virtually planar, with a dihedral angle of 1.98 (3)° between the fused five- and six-membered rings. The substituted aromatic ring is oriented at a dihedral angle of 57.50 (3)° with respect to the phthalide ring system. In the crystal structure, inter-molecular O-H⋯O and N-H⋯O hydrogen bonds link the mol-ecules, forming a three-dimensional network.
