title: 4-Chloro-3-ethyl-phenol.
abstract: The title compound, C8H9ClO, packs with two independent mol-ecules in the asymmetric unit, without significant differences in corresponding bond lengths and angles, with the ethyl group in each oriented nearly perpendicular to the aromatic ring having ring-to-side chain torsion angles of 81.14 (18) and -81.06 (19)°. In the crystal, mol-ecules form an O-H⋯O hydrogen-bonded chain extending along the b-axis direction, through the phenol groups in which the H atoms are disordered. These chains pack together in the solid state, giving a sheet lying parallel to (001), via an offset face-to-face π-stacking inter-action characterized by a centroid-centroid distance of 3.580 (1) Å, together with a short inter-molecular Cl⋯Cl contact [3.412 (1) Å].
