There are two independent molecules in the asymmetric unit of the title compound, C10H9NO3, in both of which, all non-H atoms except for the methyl C atom lie nearly in the same plane [maximum deviations = 0.094 (3) and 0.043 (2) Å]. In the crystal, each independent molecules is linked by pairs of C—HO interactions, generating inversion dimers with R22(10) ring motifs.
