Definition
ChEBI: An organochlorine pesticide consisting of 1,3-diphenylurea having chloro substituents at the 3-, 4- and 5'-positions and a 4-chloro-2-sulfophenoxy group at the 2'-position.
Production Methods
Sulcofuron is commercially synthesised through a multi-step process that constructs its complex sulfonylurea structure. The synthesis typically begins with the preparation of 4,4'-dichloro-2-nitrodiphenyl ether, formed by reacting p-chlorophenol with 2,5-dichloronitrobenzene in the presence of potassium hydroxide at elevated temperatures. This intermediate is then subjected to further transformations including reduction, urea formation, and sulfonation to yield the final active ingredient.
