The asymmetric unit of the title compound, C8H9NO3, contains two crystallographically independent molecules, whose aromatic rings are oriented at a dihedral angle of 83.29 (3)°. In the crystal structure, intermolecular O—H⋯O hydrogen bonds link the molecules into chains.
The title compound is an intermediate in the synthesis of the monomer 2-methyl-3-nitrobenzaldehyde, utilized to synthesize ergoline derivatives which have potential use in the treatment of Parkinson’s disease, see: Kozikowski et al.
