Abstract: In the molecule of the title compound, C₁₅H₁₁NO₄, the essentially planar phthalide group is oriented at a dihedral angle of 56.78 (5)° with respect to the substituted aromatic ring. An intramolecular N-HO hydrogen bond results in the formation of a non-planar six-membered ring, which adopts a nearly flattened-boat conformation. In the crystal structure, intermolecular C-HO, O-HO and N-HO hydrogen bonds link the molecules, generating centrosymmetric R₂²(8) and R₂²(11) ring motifs and forming a three-dimensional network.
