| Chemical Properties | Crystals. Insoluble in water
and kerosene; soluble in acetone and dimethylformamide. | | Uses | Herbicide. | | Production Methods | Commercial manufacture of swep is based on a straightforward carbamate forming sequence: producers first generate the key aromatic amine, 3,4 dichloroaniline, then react it with methyl chloroformate (or an equivalent carbamoylating agent) under controlled, typically alkaline, conditions to form the carbamate linkage. The process is optimised to minimise side reactions such as over acylation or hydrolysis, and the resulting crude product is purified by standard solvent based processes and crystallisation to yield technical grade swep. | | Definition | ChEBI: SWEP is a carbamate ester. | | Hazard | Toxic by ingestion. | | Mechanism of action | Interferes with metabolic processes and inhibits cell division at the growth point | | Pesticide Type | Herbicide |
