Filbertone is the principal flavor compound of hazelnuts. It is used in perfumery and is designated as generally recognized as safe (GRAS) for use in food products.

Because filbertone is found in hazelnut oil, its presence can be used to detect the adulteration of olive oil with less expensive hazelnut oil.

The natural compound is a mixture of both enantiomers, and its composition can vary depending on the source.
