| Product features | Tetrahydrothiophene (THT), a colorless and transparent liquid, is volatile and has a strong odor. It is a saturated heterocyclic compound containing sulfur, consisting of a five-membered ring with 4 carbon atoms and 1 sulfur atom, with all bonds being single bonds. It has relatively stable chemical properties, does not easily undergo addition reactions, and is not easily decomposed, with stable properties. |
| Uses and field | Tetrahydrothiophene is mainly used as an odorant (i.e., warning agent) for urban gases such as liquefied petroleum gas and natural gas. |
