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.
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]
2,2,5,5-tetramethyltetrahydrofuran (TMTHF) or 2,2,5,5-tetramethyloxolane (TMO) is a heterocyclic compound with the formula C 8 H 16 O, or (CH 3) 2 (C(CH 2) 2 OC)(CH 3) 2.It can be seen as derivative of tetrahydrofuran (oxolane) with four methyl groups replacing four hydrogen atoms on each of the carbon atoms in the ring that are adjacent to the oxygen.
In chemistry, 3,3,4,4-tetramethyltetrahydrofuran-2,5-dione is a heterocyclic compound with the formula C 8 H 12 O 3, or (CH 3) 2 (COC 2 COO)(CH 3) 2.It is a white crystalline solid with a pungent camphoraceous odor.
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).
