Tetrahydrothiophene is a sulfur-containing saturated heterocyclic compound obtained by catalytic hydrogenation of thiophene. After thiophene is reduced to tetrahydrothiophene, it no longer has a conjugated system and aromaticity. Therefore, tetrahydrothiophene shows the properties of general thioethers. Easily oxidized to sulfoxides and sulfones. Tetrahydrothiophene can be used as a raw material for the production of pharmaceuticals, pesticides and photochemicals.
