Butachlor is a pre-emergent chloroacetanalide herbicide. Butachlor is commonly used for weed control in rice as well as cotton, maize, wheat and other crops.

The IUPAC name of Butachlor is N-(butoxymethyl)-2-chloro-N-(2,6-diethylphenyl)acetamide. With the CAS registry number 23184-66-9, it is also named as Acetamide, N-(butoxymethyl)-2-chloro-N-(2,6-diethylphenyl)-. The product's categories are Agro-Chemicals; Herbicide; A-BAlphabetic; BI - BZ; Pesticides & Metabolites. It is pale yellow oily liquid which is soluble in acetone, ethanol, methanol, benzene and other organic solvents. It is toxic. When buring it will produce toxic nitrogen oxide and chloridate gas. So the storage environment should be well- ventilated, low-temperature and dry. Keep Butachlor separate from raw materials of food.

Preparation of Butachlor: First, we can get N-methylene 2,6-diethylaniline by paraformaldehyde and DEA. And then, reacting with chloroacetyl chloride to get N-(2,6-diethyl-phenyl)-N-chloromethyl chloroacetamide. At last, reacting with n-butanol to get the product.

Uses of Butachlor: It is a kind of selective preemergenceherbicide which is used for the control of barnyard grass in rice.
