Description and Uses

Tetrahydrothiophene is a solvent and a fuel gas odorant used in fire safety stench warning systems in underground mines. Tetrahydrothiophene was also used as an organocatalyst for the reaction between enynediones and benzoic acid to afford highly substituted furfuryl alcohol benzoates.
