1,2,3-Benzothiadiazole-7-carboxylic acid, 2,2,2-trifluoroethyl ester Usage And Synthesis

Application

1,2,3-Benzothiadiazole-7-carboxylic acid, 2,2,2-trifluoroethyl ester possesses both disease and insect resistance properties, and is particularly effective in controlling various soil-borne diseases through simple foliar spraying. FBT is especially effective against soil-borne diseases of potatoes. The recommended application concentration of fluoxetine activator is 10-20 mg/L, applied starting at the transplanting stage, every 7 days, for a total of 4 applications. This provides good control of cucumber downy mildew and powdery mildew without causing phytotoxicity.

Chemical Properties

Fluazole activated ester is odorless, light brown powder. Melting point is 94.5~95.5℃. It is easily soluble in acetone, ethyl acetate, dichloromethane, toluene and other organic solvents, n-hexane 8.5g/L, water 0.03g/L. pH 4.6, octanol-water partition coefficient (20 ℃) 2.90, saturated vapor pressure (25 ℃) 3.31 × 10-4Pa. It is stable at room temperature, non-combustible, with an exothermic effect of less than 500J/g at 50-500 ℃, non-explosive and non-corrosive to packaging materials. Explosive hazard, non-corrosive to packaging materials. Mixed with water, ammonium dihydrogen phosphate, iron powder and kerosene, no obvious reaction is found, there is no oxidation-reduction/chemical incompatibility; in 0.1mol/L KMnO4 solution, the color changes, there is oxidation-reduction/chemical incompatibility. 5% fluazole activated ester emulsifiable concentrate has the smell of aromatic compounds, yellowish-brown transparent liquid, density of 0.93g/ml, flash point of 55.0 ℃, non-explosive and corrosive. corrosive.
