摘要：
In the crystal structure of the title compound, C12H9NO4, the disordered pyran ring adopts a half-chair conformation. Weak intermolecular C-H...O hydrogen bonds link molecules into centrosymmetric dimers, which generate R-2(1)(6), R-2(2)(10) and R-2(2)(14) rings. In addition, pi-pi stacking interactions are present.
