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.

Chemical Properties

Appearance Colorless liquid
Boiling Point 66 °C
CAS Number 109-99-9
Density 0.8892 g/cm3
Dipole Moment 1.63 D (gas)
EINECS Number 203-726-8
HS Code 29321100
IUPAC Name Oxacyclopentane
Main Hazards Tetrahydrofuran is having intolerable odor and irritation; respiratory injury may occur at higher levels. Ingestion of tetrahydrofuran causes irritation of mouth and stomach. Tetrahydrofuran if contacted with either liquid or vapor may cause burns of eyes. Liquid produces frostbite-type of skin burn if free to evaporate; if confined to skin, burn may cause skin sensitization; not readily absorbed in toxic amounts.
