Description
Colorless, transparent liquid with an ether-like odor. Tetrahydrofuran (THF) is a strong solvent for natural and synthetic resins, especially vinyls. It is used in the manufacture of coatings, adhesives, magnetic tapes, printing inks, and Cellophane. Because THF is soluble in both water and organic solvents, it is chosen as an intermediate carrier in liquid chromatography solvent cycles.
