Tetrahydrofuran (THF), or oxolane, is an organic compound with the formula (CH 2) 4 O. The compound is classified as heterocyclic compound, specifically a cyclic ether. It is a colorless, water-miscible organic liquid with low viscosity. It is mainly used as a precursor to polymers. [8] Being polar and having a wide liquid range, THF is a ...

Screenshot of the CAS Common Chemistry database with information about caffeine ().. A CAS Registry Number [1] (also referred to as CAS RN [2] or informally CAS Number) is a unique identification number, assigned by the Chemical Abstracts Service (CAS) in the US to every chemical substance described in the open scientific literature, in order to index the substance in the CAS Registry.
2-Methyltetrahydrofuran (2-MeTHF) is an organic compound with the molecular formula C 5 H 10 O. It is a highly flammable, mobile liquid. It is mainly used as a replacement for Tetrahydrofuran (THF) in specialized applications for its better performance, such as to obtain higher reaction temperatures, or easier separations (as, unlike THF, it is not miscible with water).
Deuterated tetrahydrofuran (d 8-THF) is a colourless, organic liquid at standard temperature and pressure. [1] This heterocyclic compound has the chemical formula C 4 D 8 O, and is an isotopologue of tetrahydrofuran. [2] Deuterated THF is used as a solvent in NMR spectroscopy, though its expense can often be prohibitive. [citation needed]
Tetrahydrofurfuryl alcohol (THFA) is an organic compound with the formula HOCH 2 C 4 H 7 O. In terms of its structure, it consists of a tetrahydrofuran ring substituted in the 2-position with a hydroxymethyl group.
