2-Acetylpyridine is an organic compound with the formula CH3COC5H4N. It is a viscous colorless liquid that is widely used as a flavoring substance. It is found in malt and produced by the Maillard reaction and by nixtamalization. It contributes to the flavor of corn tortillas, popcorn, and beer. [3]

The compound is prepared by acylation of 2-bromopyridine via the Grignard reagent.[4]
