Verwenden
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.
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.
