3-Heptanone (butyl ethyl ketone), is a seven carbon ketone. It is a colourless liquid with a "green odour," also described as having a fruity scent and a melon-banana flavour. It is often used as a perfume/fragrance, as a solvent for cellulose, nitrocellulose, or vinyl resins, and as a synthetic building block in the preparation of other organic molecules.
