WIPO Patent Application WO/2020/133022
Kind Code:
A1
Abstract:
The present invention relates to a Cypyrafluone dimethylamine salt, a preparation method therefor, and use thereof. The present invention specifically relates to a crystal form A of the Cypyrafluone dimethylamine salt, and the X-ray powder diffraction spectrum has characteristic peaks at diffraction angles 2θ of 6.6°, 9.5°, 10.4°, 12.5°, 12.9°, 13.2°, 15.0°, 15.5°, 16.1°, 16.4°, 16.8°, 18.3°, 19.0°, 19.8°, 20.5°, 22.3°, 23.8°, 24.3°, 25.5°, 25.9°, 26.8°, 27.5°, 28.5°, 28.9°, 29.6°, 30.8°, 32.0°, 33.2°, 34.6°, 35.8°, 36.8°, 37.2°, 38.5°, 40.1°, 41.0°, 41.6°, and 42.4°, wherein the 2θ error range is within ±0.2°. The Cypyrafluone dimethylamine salt has good physical and chemical stability, high solubility and high bioactivity, and can be used for preventing common weeds in wheat fields.
