2-[(3,5-Di-tert-butyl-4-hydroxybenzyl)sulfanyl]benzoic acid

In the title compound, C22H28O3S, the dihedral angle between the two aromatic rings is 80.56 (6)°. The hydroxy group is shielded by the two sterically hindered tert-butyl groups and therefore is not involved in any hydrogen bonding. The C—O—H fragment is coplanar with the aromatic ring, the dihedral angle between them being 7(5)°. In the crystal structure, pairs of molecules are hydrogen bonded across crystallographic centers of symmetry.
