General description

Ethofumesate-2-keto is a metabolite of the herbicide, ethofumesate used for the control of weeds in strawberry and beet crops. It inhibits the growth of meristems, retards cellular division and limits the formation of cuticules.

Application

Ethofumesate-2-keto may be used as an analytical reference standard for the determination of the analyte in strawberries and soil samples using quick, easy, cheap, effective, rugged, and safe (QuEChERS) method of extraction followed by gas chromatography (GC)/liquid chromatography (LC) coupled to tandem mass spectrometry (MS/MS) and two-dimensional gas chromatography time-of-flight mass spectrometry (GC × GC-TOF-MS).
Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.
