In the title compound, C10H9NO3, the dihedral angle between the benzofuran ring system (r.m.s. deviation for the non-H atoms = 0.009 Å) and the -C-C(O)-N- segment is 83.76 (1)°. In the crystal, molecules are linked by N-HO and O-HO hydrogen bonds, generating (001) sheets, which feature C(4) and C(10) chains.
