Tetrahydrofuran CAS 109-99-9

Tetrahydrofuran, abbreviated THF, is a heterocyclic organic compound. It belongs to the group of ethers and is the product of the complete hydrogenation of the aromatic compound furan. Tetrahydrofuran is one of the strongest polar ethers, used as a moderately polar solvent in chemical reactions and extraction, colorless volatile liquid at room temperature, with an odor similar to ether. Soluble in water, ethanol, ether, acetone, benzene and other organic solvents, known as the “universal solvent”. Room temperature and water can be partially miscible, part of the illegal reagent business is to take advantage of this point on the tetrahydrofuran reagent to water profiteering. Since THF has the tendency to form peroxide in storage, industrial products are usually added with antioxidant BHT. moisture content ≦0.2%. It is characterized by low toxicity, low boiling point and good fluidity.
