n-Butyl acetate, also known as butyl ethanoate, is an ester that is a colorless, flammable liquid at room temperature. It is found in many types of fruit, where along with other chemicals, it imparts characteristic flavors and has a sweet smell of banana or apple.
It is used as a synthetic fruit flavoring in foods such as candy, ice cream, cheeses, and baked goods. Butyl acetate is often used as a high-boiling solvent of moderate polarity. It is also used as a solvent in nail polish along with ethyl acetate.
