| | 2,5-Dimethylfuran Usage And Synthesis |
| Chemical Properties | clear colorless to amber liquid | | Chemical Properties | Colorless liquid; spicy smoky aroma | | Occurrence | Reported found in beef, chicken, cocoa, coffee, egg, malt, rice, and rum. | | Uses | 2,5-Dimethylfuran is a major metabolite of hexane with singlet oxygen scavenging ability. It is used as biofuel, biomaker for smoking, pharmaceutical intermediate and in organic synthesis. It is also used to analyze samples for the derivatization of carbonyl-containing compounds to their oximes. | | Uses | It is an ideal marker for detecting cigarette smoke. | | Definition | ChEBI: 2,5-dimethylfuran is a member of the class of furans that is furan in which the hydrogens at positions 2 and 5 are replaced by methyl groups. It has a role as a human urinary metabolite, an antifungal agent, a bacterial metabolite, a fumigant, a fuel, a plant metabolite and a Maillard reaction product. | | Aroma threshold values | Medium strength odor, meaty type; recommend smelling in a 10.0% solution or less.
| | Taste threshold values | Chemical meaty gravy taste at 30 ppm in water. | | Synthesis Reference(s) | The Journal of Organic Chemistry, 54, p. 3475, 1989 DOI: 10.1021/jo00275a039
Synthesis, p. 209, 1973 | | General Description | Clear yellow oily liquid. Aromatic caustic odor. | | Air & Water Reactions | Highly flammable. 2,5-Dimethylfuran may be sensitive to exposure to air(not vigorous). Insoluble in water. | | Reactivity Profile | 2,5-Dimethylfuran can react vigorously with oxidizing materials. 2,5-Dimethylfuran is also incompatible with strong acids and strong bases. | | Fire Hazard | 2,5-Dimethylfuran is flammable. |
