Chemical Properties
2-Acetylfuran is a gold-colored solid with an odor of sweet balsam almond cocoa, caramel
coffee. It is incompatible with strong oxidizing agents, strong reducing agents, and strong
bases. It is combustible. On decomposition, 2-acetylfuran releases carbon monoxide and carbon
dioxide. It is insoluble in water, but soluble in alcohol, dipropylene glycol, and ethyl ether.
Health Hazard
Exposures to 2-acetylfuran by ingestion, inhalation, and skin absorption cause harmful
effects. It causes irritation to the skin, the eyes, coughing, respiratory tract irritation, and
respiratory distress. Accidental ingestion causes irritation of the digestive tract. There are
no data about chronic exposure and adverse effects.
Occurrence
Reported found as a constituent in coffee aroma; also isolated from beech and oak wood tar oils; an aroma
component of yellow passion fruit (Passiflora edulis f. flavicarpa); also a volatile flavor component of potato chips. Also reported in
tomato paste, roasted beef, grilled pork, beer, rum, red wine and green tea.
Uses
2-Acetylfuran is a widely used reagent in manufacturing pharmaceuticals and aroma compounds.
