Sumario:The reaction of 2-carboxy­benzaldehyde and hydrazine hydrate unexpectedly yielded the title compound, C(16)H(10)N(2)O(3), which comprises one phthalide ring, one phthalazine system and a chiral centre. The phthalide unit is almost perpendicular to the phthalazine system, forming a dihedral angle of 87.1 (3)°. The packing is governed by weak C—H⋯O hydrogen-bonding inter­actions, forming layers parallel to the ab plane.
