What is Alachlor?

Plain description, key identifiers and synonyms

Alachlor is an aromatic amide that is N-(2,6-diethylphenyl)acetamide substituted by a methoxymethyl group at at the nitrogen atom while one of the hydrogens of the methyl group has been replaced by a chlorine atom. 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.
