CAS No.: 109-99-9
Molecular Formula: C4H8O                                        Molecular Weight:72.11
Structural Formula:
  

Property:
Tetrahydrofuran (THF) is an organic compound with the formula (CH2)4O. It is a colorless, water-miscibleorganic liquid with low viscosity at standard temperature and pressure. This heterocyclic compound has the chemical formula (CH2)4O. 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. THF has an odor similar to its chemical cousin, diethyl ether, but is a much less potent anesthetic than diethyl ether. 

Specifications:

Application:
THF can be polymerized by strong acids to give a linear polymer called poly(tetramethylene ether) glycol(PTMEG), also known as PTMO, polytetramethylene oxide. The primary use of this polymer is to make elastomeric polyurethane fibers like Spandex.
The other main application of THF is as an industrial solvent for PVC and in varnishes.It is an aproticsolvent with a dielectric constant of 7.6. It is a moderately polar solvent and can dissolve a wide range of nonpolar and polar chemical compounds.THF is water-miscible, and can form solid clathrate hydrate structures with water at low temperatures.
