Tetrahydrofuran (THF), or oxolane, is an organic compound with the formula (CH2)4O. The compound is classified as heterocyclic compound, specifically a cyclic ether. It is a colorless, water-miscible organic liquid with low viscosity. It is mainly used as a precursor to polymers.[8] Being polar and having a wide liquid range, THF is a versatile solvent.

Tetrahydrofuran (THF) is commonly used as solvent, reaction medium, and starting material for various syntheses in the chemical industry, for example, for preparing adhesives, special paints, coatings, fibers, in the extraction of specific active substances, for recrystallization of certain compounds or as starting 

In the laboratory, THF is a popular solvent when its water miscibility is not an issue. It is more basic than diethyl ether and forms stronger complexes with Li+, Mg2+, and boranes. It is a popular solvent for hydroboration reactions and for organometallic compounds such as organolithium and Grignard reagents.
