product description

Excellent Odor Detection Performance: Tetrahydrothiophene can be detected in air at concentrations as low as 0.01 ppm, providing highly effective leak-warning performance.


Stable and Long-Lasting Odorant: It offers good chemical stability and is not easily lost by volatilization, ensuring reliable long-term odorization in gas systems.


Non-Corrosive to Equipment and Pipelines: The product is non-corrosive to gas equipment, transportation pipeline gaskets, and related materials, helping protect infrastructure integrity.


No Olfactory Fatigue Risk: It does not cause habitual desensitization of the human sense of smell, making it a safer and more dependable odorant for LPG and natural gas applications.


Product Description of Tetrahydrothiophene CAS#110-01-0

Tetrahydrothiophene is a colorless volatile cyclic thioalkane, insoluble in water but soluble in common organic solvents.

It has a pungent recognizable smell detectable at ultra-low concentration, featuring stable property and low volatility. Non-corrosive and free of olfactory fatigue, it is widely used as high-grade odorant for natural gas and liquefied gas to replace ethyl mercaptan.


Product Application of Tetrahydrothiophene CAS#110-01-0

Tetrahydrothiophene serves as solvent and fuel gas odorant, ideal for mine fire safety leakage alert. It also acts as an organic catalyst to synthesize substituted furfuryl alcohol benzoates.
