Tetrahydrofuran

Tetrahydrofuran is a heterocyclic compound. As one of the most polar ethers with a wide liquid range, it is a useful solvent. Its main use, however, is as a precursor to polymers. Tetrahydrofuran has an odor similar to its chemical cousin, diethyl ether, but is a much less potent anesthetic than diethyl ether.
