Coffee furanone (2-methyltetrahydrofuran-3-one) is a pleasant smelling liquid furan derivative which is a volatile constituent of the aroma complex of roasted coffee. Coffee furanone is less odorous than furfuryl mercaptan which with an odor threshold of 0.005 ppb was the first high impact aroma chemical but has a very pleasant sweet caramel character with some nuttiness.
