摘要:
#$%^&*AU2013202748A120130502.pdf#####ABSTRACT The present invention relates to novel crystalline polymorphic and amorphous forms of the compound (E)-2-{2-[6-(2-cyanophenoxy) pyrimidin-4-yloxy] phenyl}-3-methoxyacrylate (azoxystrobin). Infrared Raman spectra, X-ray powder diffraction pattern and differential scanning calorimetry thermogram of two polymorphs A and B are provided. Further, the present invention also provides methods for preparing the novel polymorphic forms A and B, as well as processes for producing mixtures of the polymorphs, and a process for preparing amorphous azoxystrobin. Yet further, the present invention provides anti-fungal compositions comprising the novel crystalline polymorphs A and B or amorphous azoxystrobin, which are useful for controlling and combating fungi grown on agricultural and horticultural crops and up-land, and methods of using the same as pesticidal agents for combating fungi on agricultural and horticultural crops.
