White to Off-White Solid
The Uses of Metazachlor
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.
