Description

General description

Metolachlor is used for the control of broadleaf weeds and annual grasses primarily in corn, soybean, and sorghum. Active compounds of metolachlor pesticide may be converted by the target insects or plants or may be degraded in the environment to form the corresponding oxanillic (OA) acids. Metolachlor OA is one of the metabolite of metolachlor.[1]

Application

Metolachlor OA may be used as an analytical reference standard for the determination of the analyte in water by solid phase extraction and liquid chromatography/electrospray ionization tandem mass spectroscopy (LC/ESI MS/MS).[1]
