General overview of Tetrahydrofuran THF CAS 109-99-9

Tetrahydrofuran (Tetrahydrofuran) is a heterocyclic organic compound with a molecular formula of C4H8O. It belongs to the ethers and is a completely hydrogenated product of the aromatic compound furan. It is a colorless, water-miscible, organic liquid with a small viscosity at normal temperature and pressure. The chemical formula of this cyclic ether can be written as (CH2)4O. Because of its long liquid range, it is a commonly used medium-polar aprotic solvent. Its main purpose is to be the precursor of high molecular polymers. Although the odor and chemical properties of THF are very similar to those of ether, the anesthetic effect is very poor.
