title: 6-Hy-droxy-2H-1,3-benzodioxole-5-carbaldehyde.
abstract: The title compound, C(8)H(6)O(4), crystallizes with two independent mol-ecules in the asymmetric unit. The benzodioxole ring system is almost planar in each mol-ecule, with maximum deviations of 0.008 (1) and 0.007 (1) Å. The mol-ecular structure is characterized by strong electrostatic intra-molecular O⋯O contacts [2.649 (3) Å] and intra-molecular O-H⋯O hydrogen-bonding inter-actions. Inter-molecular O⋯O inter-actions [3.001 (2) Å] are observed in the crystal structure.
