Chemical Properties

clear colorless to yellow liquid

Uses

In a comparative study of aromatic fluorodenitration with Potassium fluoride, in several dipolar aprotic solvents, a much faster reaction rate was observed with DMSO or tetramethylene sulfoxide than with the more commonly used Sulfolane.

Definition

ChEBI: Tetrahydrothiophene 1-oxide is a member of tetrahydrothiophenes.
