| Hazard Information | Back Directory | [Description]
Difenzoquat metilsulfate is a herbicide mainly used to control wild oats. It is highly soluble in water and has a low volatility. It can be environmentally persistent depending on local conditions. It tends to be moderately toxic to biodiversity. Difenzoquat metilsulfate is also moderately toxic to mammals via the oral route. | [Chemical Properties]
The pure product is a white, hygroscopic solid. Its mp is 155-157°C, vapor pressure is 1.33×10-5 Pa (20°C), and relative density is 1.13. Its solubility in water is 76% at 25°C, 78% at 37°C, and 85% at 56°C. It is slightly soluble in methanol and ethanol, but insoluble in petroleum hydrocarbons. Its aqueous solution (pH 3-3.4) is stable to light and acidic conditions, but unstable to alkali, with no effect upon storage at 120°C for 169 hours. The commercial product has a content of >96% and an mp of 150-160°C. | [Uses]
DIFENZOQUAT METHYLSULFATE is Herbicide; agricultural fungicide.
| [Uses]
DIFENZOQUAT METHYLSULFATE is used to control wild oats in wheat, barley, ?ax, maize, rye grass, vetches and rye grass crops.
| [Production Methods]
Difenzoquat metilsulfate is commercially synthesized via a process that begins by reacting 1-methyl-3,5-diphenylpyrazole with concentrated sulfuric acid and methanol at elevated temperatures (~160 DegC), where methanol is gradually distilled and replenished to drive the reaction forward. After sulfonation, the mixture is cooled and treated with 1,2-dichloroethane to facilitate crystallisation and purification of the final product. | [Mechanism of action]
Selective, absorbed by foliage. Acts via the rapid destruction of cell membranes. | [Safety Profile]
Poison by ingestion. Moderatelytoxic by skin contact. When heatedto decomposition it emits very toxic fumes of NOx andSOx. | [Environmental Fate]
Soil. Though no products were reported, the half-life in soil is approximately 3 months (Hartley and Kidd, 1987).
Photolytic. Degrades photolytically to the volatile monomethyl pyrazole (Hartley and Kidd, 1987).
Chemical/Physical. May react with aluminum releasing hydrogen (Hartley and Kidd, 1987). | [Pesticide Type]
Herbicide; Fungicide |
