Izoamila acetato estas organika komponaĵo apartenanta al la funkcia grupo de la esteroj estigita per interagado de la acetata acido kaj izopentanolo en ĉeesto de sulfata acido. Ĝi estas senkolora likvaĵo kun forta kaj agrabla odoro, iomete solvebla en akvo kaj tre solvebla en organikaj solvantoj. Pro ĝia intense agrabla odoro kaj malalta tokseco ĝi uzatas en nutro-industrio kiel gustigilo kaj odorigilo. Izoamil-acetato nature okazas en bananujo kaj ankaŭ ĝi estas sinteze produktata.
