2,5-Dimethylfuran Usage And Synthesis
Chemical Propertiesclear colorless to amber liquid
Chemical PropertiesColorless liquid; spicy smoky aroma
OccurrenceReported found in beef, chicken, cocoa, coffee, egg, malt, rice, and rum.
Uses2,5-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.
UsesIt is an ideal marker for detecting cigarette smoke.
DefinitionChEBI: 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 valuesMedium strength odor, meaty type; recommend smelling in a 10.0% solution or less.
Taste threshold valuesChemical meaty gravy taste at 30 ppm in water.
