| | Thiobencarb Usage And Synthesis |
| Chemical Properties | Amber-colored, slightly water-soluble,
liquid. | | Uses | Thiocarbamate herbicide used to control sedges
and grasses in rice paddies. | | Definition | ChEBI: Thiobencarb is a member of monochlorobenzenes and a monothiocarbamic ester. | | Production Methods | Thiobencarb is produced commercially through a multi-step synthesis that constructs its thiocarbamate herbicidal structure. The process begins with the preparation of diethylthiocarbamic acid, which is then esterified with 4-chlorobenzyl chloride to form S-(4-chlorobenzyl) diethylthiocarbamate, the active thiobencarb molecule. This reaction is typically carried out under controlled temperature and pH conditions to ensure high yield and purity. The final product is then purified and formulated. | | General Description | Pale yellow to brownish yellow liquid. Non corrosive. Used as an herbicide. | | Air & Water Reactions | Thio and dithiocarbamates slowly decompose in aqueous solution to form carbon disulfide and methylamine or other amines. Such decompositions are accelerated by acids. | | Reactivity Profile | Thiobencarb is a thiocarbamate. Flammable gases are generated by the combination of thiocarbamates and dithiocarbamates with aldehydes, nitrides, and hydrides. Thiocarbamates and dithiocarbamates are incompatible with acids, peroxides, and acid halides. | | Hazard | Toxic. | | Mechanism of action | Selective. Acetyl CoA carboxylase inhibitor (ACCase) - distrupts fatty acid biosynthesis and lipid formation. | | Pesticide Type | Herbicide |
