General description

Clethodim is a cyclohexanedione oxime herbicide primarily used against a wide variety of broadleaf crops. Its mode of action involves the inhibition of acetyl-coenzyme A carboxylase.

Application

Clethodim may be used as a reference standard for the determination of clethodim in crops by liquid chromatography (LC) followed by liquid chromatography/mass spectrometry (LC/MS) with electrospray ionization (ESI).
Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.
