The three rings in the molecule of the title compound, C14H12OS, are planar, with the methyl and methoxy groups coplanar with the rest of the molecule. The average C-S distance of the thiophene moiety is 1.737 (3) Angstrom. The crystal structure is composed of discrete molecules separated by van der Waals contacts.
