2,5-Dimethylfuran Chemical Properties,Usage,Production

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.
