What does furane mean?
Furane is an alternative spelling of furan, the simplest oxygen-containing heterocyclic compound, with the formula C4H4O. It is a colourless, highly volatile and flammable liquid whose five-membered ring — four carbon atoms and one oxygen atom — serves as a fundamental structural motif in organic chemistry. Industrially, furane has been valued as a solvent and as a starting material for making resins, pharmaceuticals, and other fine chemicals. The name traces back to Latin furfur, meaning bran, reflecting the compound family's discovery in materials derived from agricultural by-products such as bran and oat hulls. Although 'furane' appears in older textbooks and remains in occasional use in some European technical writing, modern nomenclature strongly favours 'furan', so readers today most often meet 'furane' in historical or regional sources rather than contemporary research papers.
nounAn alternative spelling of furan, a colourless, volatile, flammable heterocyclic liquid (C4H4O) with a five-membered ring containing one oxygen atom, used as an industrial solvent and chemical intermediate.
- As an alternative spelling of furan: the heterocyclic organic compound C4H4O, a volatile flammable liquid used as a solvent and building block in chemical synthesis.
"The chemist distilled a small quantity of furane to use as a solvent in the synthesis."
"The laboratory kept drums of furane on hand because it was an effective solvent for resins."
"Early twentieth-century German journals routinely printed the compound's name as furane rather than furan."
The word 'furane' takes its name from Latin furfur — bran — because chemists first isolated its cousin furfural from bran and other agricultural waste.

Etymology of furane
The name furane was coined in the nineteenth century from Latin furfur, meaning bran or husks, since related compounds such as furfural were first obtained from bran, oat hulls, and similar materials. The spelling 'furane' spread through continental European chemical literature, while English-language usage gradually settled on 'furan' as the standard form. Cognate terms sharing the furfur root include furfural, furfuran, and the adjective furfuraceous.
How furane is actually used
The spelling 'furane' is now largely superseded by 'furan', which is preferred by IUPAC and virtually universal in current chemistry; encountering 'furane' usually indicates older literature or certain continental European conventions.
Easily confused with furane
Furan is the standard modern IUPAC spelling of the identical compound, while 'furane' is an older alternative spelling still seen in some European and technical literature.
'Furore' (or furor) means an outburst of enthusiasm or anger, whereas furane refers to the organic chemical compound; the two share only a superficial visual resemblance.
