Beschreibung

Allgemeine Beschreibung

Acetophenone is a colourless liquid with a sweet pungent taste. It can be used in perfume industry, as a fragrance ingredient and also as a flavouring agent in food industries.

Anwendung

Acetophenone can stimulate the reductive alkylation of aniline to form N-phenyl-alpha-methylbenzylamine. It can also undergo coupling reaction, catalyzed the copper under molecular oxygen in the presence of boron trifluoride etherate as an additive, to give 1-(4-aminophenyl)-2-phenylethane-1,2-dione.

Acetophenone may be used as an analytical reference standard for the determination of the analyte in perfumes and different varieties of African star apple fruit (Chrysophillum albidum) by chromatography techniques.

Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.
