Description

General description

trans-2-Nonenal (T2N) is a volatile unsaturated aldehyde with an unpleasant greasy odor, present in low concentrations in barley, malt, and certain vegetables. It is utilized as an insect repellent, insecticide, and flavor compound. T2N is one of the basic components contributing to the off-flavor and odor in stored beer.

Application

trans-2-Nonenal (T2N) may be used as a reference standard for the determination of the analyte in barley and malt samples by analytical methods.
