The benzene rings form dihedral angles of 12.10 (13) and 25.17 (12)° with the thio-phene ring. The dihedral angle between the two benzene rings is 17.59 (14)°. There are two intra-molecular O-H⋯N hydrogen bonds. In the crystal, N-H⋯O hydrogen bonds connect mol-ecules into chains along [010].Acta crystallographica.
