Filbertone is the principal flavor compound of hazelnuts.cite-ref-1[1] It is used in perfumery and is designated as generally recognized as safe (GRAS) for use in food products.cite-ref-2[2]

Because filbertone is found in hazelnut oil, its presence can be used to detect the adulteration of olive oil with less expensive hazelnut oil.cite-ref-3[3]cite-ref-4[4]

The natural compound is a mixture of both enantiomers, and its composition can vary depending on the source.cite-ref-5[5]cite-ref-6[6]
