Raspberry ketone

Synonyms: 4-(4-Hydroxyphenyl)-2-butanone, Frambinone, Rheosmin, Oxyphenylon, Raspberry Ketone

Raspberry ketone is a naturally occurring phenolic compound responsible for the characteristic sweet, fruity aroma of red raspberries. While its natural content in raspberries is extremely low (typically 1–4 mg per kg of fruit), commercial production relies on chemical synthesis to meet global demand. The compound was first isolated in the 1920s and has since become a key ingredient in flavors, fragrances, and dietary supplements.

Chemically, raspberry ketone belongs to the class of phenylbutanoids and is structurally related to other aromatic compounds such as capsaicin and gingerol. Its molecular structure features a 4-hydroxyphenyl group linked to a butanone chain, which contributes to its characteristic odor and biological activities. The synthetic route typically involves a Claisen-Schmidt condensation followed by catalytic hydrogenation, yielding high-purity material.

Raspberry ketone is standardized to ≥98% purity (HPLC) for use in food, pharmaceutical, and nutraceutical applications. It is widely employed as a flavoring agent in beverages, confectionery, and chewing gum, as well as in perfumery for its fruity note. In the supplement industry, it is marketed for weight management and metabolic support, although clinical evidence remains limited.
