Levoglucosenone is an organic compound with the formula [OCH₂(CH)₄CO₂]. A pale yellow liquid, it is an unsaturated bicyclic ketone-diether formed from levoglucosan by loss of two molecules of water. As a product of the acid-catalysed pyrolysis of cellulose, _D-glucose, and levoglucosan, this liquid hydrocarbon is of interest as a biofuel and biofeedstock.
