Since its establishment, Qingdao Xupu Supply Chain Co., Ltd. has been dedicated to the research and development of tetrahydrothiophene odorants. Xupu Chemical is highly capable, values credibility, honors contracts, and ensures product quality, earning the trust of a wide range of individuals in need through its diverse product offerings. The tetrahydrothiophene we produce is primarily used for natural gas odorant applications. Due to excessive market demand and to meet the needs of market development, Xupu Chemical continues to develop high-end products, providing individuals in need with a more comprehensive and safer range of gas odorants.

Tetrahydrothiophene (abbreviated as THT) is a sulfur-containing saturated heterocyclic compound obtained through the catalytic hydrogenation of thiophene. After thiophene is reduced to tetrahydrothiophene, it no longer possesses a conjugated system or aromaticity. As a result, tetrahydrothiophene exhibits the properties of a general thioether, being easily oxidized to sulfoxides and sulfones (sulfolane).
Our products have now passed the SGS quality certification under the international standards system, with product quality meeting international standards and gaining widespread recognition from domestic and international clients. The completion of the tetrahydrothiophene project by Qingdao Xupu Supply Chain Co., Ltd. has fully achieved the import substitution of natural gas odorants.
