| | pyroxasulfone Usage And Synthesis |
| Uses | Pyroxasulfone is an inhibitor of the biosynthesis of very-long-chain fatty acids. Pyroxasulfone is also used to control grass weed species in pre-emergence in major field crops. | | Production Methods | Pyroxasulfone is commercially synthesised through a multi-step process that builds its unique isoxazoline-sulfonyl-pyrazole structure. The synthesis typically begins with the preparation of a substituted pyrazole intermediate, such as 5-(difluoromethoxy)-1-methyl-3-(trifluoromethyl)-1H-pyrazol-4-ylmethanol, which is then reacted with a sulfonylating agent and coupled to a dimethylisoxazoline moiety. This process involves selective fluorination, methylation, and sulfonylation steps under controlled conditions to ensure high purity and herbicidal efficacy. | | Mechanism of action | Inhibition of very long chain fatty acids (VLCFA, inhibition of cell division) | | Pesticide Type | Herbicide |
