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.
Pyrazoline is a heterocyclic chemical compound with the molecular formula C3H6N2. Pyrazolines are well-known and important nitrogen-containing five-membered ring heterocyclic compounds. Pyrazoline derivatives have numerous prominent pharmacological effects, such as antimicrobial, anti-inflammatory, analgesic, antidepressant and anticancer.
