General description

Orbencarb is a pre-emergence, thiocarbamate herbicide, generally synthesized by the reaction of 2-chloro-mercaptotoluene with N-diethyl carbamoyl chloride. It is highly effective against weeds in upland crops such as wheat and soy bean.

Application

Orbencarb may be used as an analytical reference standard for the quantification of the analyte in water samples using cyclodextrin-modified micellar electro-kinetic chromatography (MEKC).
Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.
