Tetrahydrofuran, often abbreviated as THF, is a colorless, organic compound with a distinctive ether-like odor. It is a cyclic ether and is commonly used as a solvent in various chemical reactions and processes due to its ability to dissolve a wide range of polar and nonpolar substances. In addition to its role as a solvent, THF is also utilized in the production of polymers, such as polytetrahydrofuran, which is used to make elastic fibers and plastics. Its low boiling point and high solvency make it valuable in laboratories and industrial applications.
