Abstract: The asymmetric unit of the title compound, C9H12O4, consists of two crystallographically independent mol­ecules with similar conformations: essentially planar [r.m.s deviations for C6O4 = 0.0057 and 0.0137 Å] except for the central meth­oxy-methyl group [C-C-O-C torsion angles = 83.3 (2) and 83.9 (2)°]. In the crystal, O-H...O hydrogen bonds link the mol­ecules, generating supra­molecular chains along the b axis.The three-dimensional crystal structure is stabilized by C-H...O and C-H...[pi] inter­actions.
