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.
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/jo00275a039Synthesis, p. 209, 1973
General Description	Clear yellow oily liquid. Aromatic caustic odor.
