| Synonyms | Oxolane, 1,4-Epoxybutane, 1-Oxacyclopentane, THF, 1,4-Butylene oxide, Cyclotetramethylene oxide fraction, Furanidin, Tetra-methylene oxide , cas 109-99-9 |
| Overview | Tetrahydrofuran is a clear, colorless, volatile liquid with an ether-like odor. It is a cyclic ether and a highly polar aprotic solvent, commonly used in polymer chemistry, organometallic reactions, and solvent applications. THF is miscible with water and most organic solvents. It can form explosive peroxides on exposure to air and light over time, requiring careful storage. |
Product Information
Tetrahydrofuran (THF) is a flammable, polar solvent used widely in organic synthesis, polymer processing, and chemical manufacturing. It can form explosive peroxides upon aging and is classified as a suspected carcinogen, requiring careful handling and storage.
