·        Tetrahydrofuran has many uses in the industrial marketplace. It is a versatile industrial solvent for natural and synthetic resins and is a solvent used in the production of nylon. It is also an industrial solvent for PVC.

·       Tetrahydrofuran is also a valuable chemical intermediate as it is a precursor to polymers, such as poly (tetra methylene ether) glycol.

·       The primary use of this polymer is the production of elastomeric polyurethane fibers like Spandex.

·       It is also an intermediate in the natural gas industry where it is a natural gas odorant.

·       It is also used as a reaction medium, primarily in the pharmaceutical industry, in processes such as Grignard syntheses or lithium aluminum hydride reductions.
