| | BENFURESATE Usage And Synthesis |
| Description | Benfuresate is a post-emergence herbicide. It has a moderate aqueous solubility and is relatively volatile. It is not persistent in soil systems but not normally persistent in water. It has a low mammalian toxicity and a low potential for bioaccumulation. It is relatively non-toxic to birds but moderately toxic to honeybees and most aquatic organisms. | | Chemical Properties | Furosemide original drug purity ≥95%, melting point 32~35℃. Pure product is gray-white crystals (industrial product is dark brown highly viscous solution), with a slight odor, melting point 30.1 ℃. Vapor pressure:1.43mPa( 20℃),2.78mPa(25℃). Relative density:0.957, Kow lgP=2.41(20℃). Solubility in water 261mg/L(25℃). Solubility in organic solvents (g/L): acetone>1050, dichloromethane>1220, toluene>1040, methanol>980, ethyl acetate>920, cyclohexane51, n-hexane15.3. Stable in aqueous solution placed at 37°C, pH 5.0, 7.0, 9.2 for 31d. 0.1mol/L sodium hydroxide DT50 in aqueous solution is 12.5d. flash point 37.5°C (determined by Abel-Pinsky method), non-flammable. | | Uses | Benfuresate may be used as a reference standard in the determination of the analyte in water and urine samples by an analytical method based on coupling photo-induced chemiluminescence in a multicommutation continuous flow methodology.', 'Refer to the productμs Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support. | | Definition | ChEBI: Benfuresate is a member of benzofurans. | | Production Methods | Benfuresate is produced through a multi-step chemical synthesis involving sulfonation and esterification of a benzofuran derivative. The process begins with the preparation of 2,3-dihydro-3,3-dimethylbenzofuran, which is then reacted with ethanesulfonyl chloride in the presence of a base such as triethylamine to form the ethanesulfonate ester. This reaction typically occurs in an organic solvent under controlled temperature conditions to ensure selectivity and minimize side reactions. | | Mechanism of action | Inhibits lipid synthesis. It acts by inhibiting the synthesis of fatty acids in plants, leading to the disruption of cell membranes and ultimately causing the death of the targeted weeds. | | Pesticide Type | Herbicide |
