Metazachlor Chemical Properties,Usage,Production

Chemical Properties

White to Off-White Solid

Uses

A chloroacetanilide herbicide used on vegetable crops.

Definition

ChEBI: An organochlorine compound that is 2-chloroacetamide substituted by a 2,6-dimethylphenyl and a (1H-pyrazol-1-ylmethyl) group at the nitrogen atom.

Metabolic pathway

Metazachlor is transformed in soil into 2-hydroxy-N- (2,6-dimethylphenyl)-N-(1H-pyrazol-1- ylmethyl)acetamide, 2-chloro-N-(2,6- dimethylphenyl)acetamide, and 4,4' -methylenebis-(2,6- dimethylbenzenamine), and the soil concentration of the benzenamine is lower than 0.1 ppm.
