Terathane container owned by DuPont (before the business was sold to Invista). The main use of polytetrahydrofuran is to make elastic fibres such as spandex (elastane) for stretchable fabrics [4] and for polyurethane resins.
5,10-Methylenetetrahydrofolate (N5,N10-Methylenetetrahydrofolate; 5,10-CH 2-THF) is cofactor in several biochemical reactions. It exists in nature as the diastereoisomer [6R]-5,10-methylene-THF. As an intermediate in one-carbon metabolism, 5,10-CH 2 -THF converts to 5-methyltetrahydrofolate , 5-formyltetrahydrofolate , and methenyltetrahydrofolate.
Borane–tetrahydrofuran is an adduct derived from borane and tetrahydrofuran (THF). These solutions, which are colorless, are used for reductions and hydroboration, reactions that are useful in synthesis of organic compounds. A common alternative to BHF•THF is borane–dimethylsulfide, which has a longer shelf life and effects similar ...

Structure of the ether complex HfCl 4 (thf) 2. [1]In chemistry, a transition metal ether complex is a coordination complex consisting of a transition metal bonded to one or more ether ligand.
Organolithium compounds bind Lewis bases such as tetrahydrofuran (THF), diethyl ether (Et 2 O), tetramethylethylene diamine (TMEDA) or hexamethylphosphoramide (HMPA). [5] Methyllithium is a special case: its tetrameric structure is unaffected by ether or even HMPA. [ 7 ]
