Raspberry ketone Cas 5471-51-2  Feature And Application 

 

Raspberry ketone Cas 5471-51-2  is a highly characteristic component of raspberry aroma. It forms colorless crystals (mp 82–83°C) with a sweet, fruity odor strongly reminiscent of raspberries. Raspberry ketone is prepared by alkali-catalyzed condensation of the alkali salt of 4-hydroxybenzaldehyde and acetone, followed by selective hydrogenation of the double bond in the resulting 4-hydroxybenzalacetone. Other syntheses start from phenol, which is converted into 4-(4-hydroxyphenyl)-2-butanone with methyl vinyl ketone or with 4-hydroxy-2-butanone.

4-(4-Hydroxyphenyl)-2-butanone is used in perfumery, in cosmetics, and as a food additive to impart a fruity odor.The primary aroma compound of red raspberries, used in perfume compositions, shampoos, cosmetics and as a food additive. Also an impurity in the synthesis of Dobutamine (D494445). Reported found European cranberry, raspberry, blackberry, loganberry and sea buckthorn (Hippophae rhamnoides L.).
