PRODUCT INTRODUCTION
description
Acetochlor is a monocarboxylic acid amide that is N-phenylacetamide carrying an ethyl and a methyl group at positions 2 and 6 respectively on the benzene ring while one of the methyl hydrogens as well as the hydrogen attached to the nitrogen atom have been replaced by a chloro and an ethoxymethyl group respectively. It has a role as a herbicide, a xenobiotic and an environmental contaminant. It is a monocarboxylic acid amide, an organochlorine compound and an aromatic amide. It is functionally related to a N-phenylacetamide.
