Beschreibung

General description

Isopentyl acetate is an alarm pheromone present in honey bees, which may affect the brain and hence, provoke a quick defensive response, thereby influencing their behavior for a longer period of time.

Application

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

Isopentyl acetate may be used as an analytical standard for the determination of the analyte in fruits, wine,[1][2] and aqueous solutions of alcohols by various gas chromatography (GC) based techniques.
