3-Bromo-2-hy-droxy-benzaldehyde.
The mol-ecule of the title compound, C(7)H(5)BrO(2), is almost planar (r.m.s. deviation from the plane of all the non-H atoms = 0.0271 Å) and displays intra-molecular O-H⋯O hydrogen bonding between the phenol group and the aldehyde O atom. Packing is directed by weak inter-molecular C-H⋯Br inter-actions and π-stacking between nearly parallel mol-ecules [dihedral angle = 5.30 (6)° and centroid-centroid distance = 3.752 (1) Å].
