Furan is a heterocyclic organic compound, consisting of a five-membered aromatic ring with four carbon atoms and one oxygen atom. Chemical compounds containing such rings are also referred to as furans.
Pyran
In chemistry, pyran, or oxine, is a six-membered heterocyclic, non-aromatic ring, consisting of five carbon atoms and one oxygen atom and containing two double bonds. The molecular formula is C5H6O. There are two isomers of pyran that differ by the location of the double bonds.
Furan
A colorless, volatile, heterocyclic organic compound, C4H4O, obtained from wood oils and used primarily in organic synthesis. Also called furfuran.
Pyran
Either of two isomeric unsaturated compounds with the formula C5H6O, having a ring of five carbon atoms and one oxygen atom.
Furan
Any of various derivatives of this compound.
