The chemical formula for tetrahydrofuran (THF), also known as Oxolane, is (CH2)4O. It is a cyclic ether and also referred to as a heterocyclic molecule, as one of each methyl group's hydrogen is replaced by oxygen. Tetrahydrofuran is a colorless organic liquid with low viscosity and moderate water miscibility. It is a polar liquid with a wide range of solubility and is abundantly utilized as a polymer precursor in various polymer production sectors. Normally, a variety of separation/purification stages are required for producing High Performance Liquid Chromatography (HPLC) grade solvents. Many distillations are employed for the removal of volatile impurities followed by the filtration to remove any solid suspended impurities.
