To provide a crystal of (E)-2-(4-tert-butylphenyl)-2-cyano-1-(1,3,4-trimethylpyrazol-5-yl) vinyl=2,2-dimethylpropionate, its preparation method and a suspension composition containing thereof. Measure to solve the problem Low-melting-point crystal or high-melting-point crystal of (E)-2-(4-tert-butylphenyl)-2- Cyano-1-(1,3,4-trimethylpyrazol-5-yl)vinyl=2,2-dimethylpropionate. A suspension Composition better in preservation stability comprising said low-melting-point crystal and dispersing media.
提供(E)-2-(4-叔丁基苯基)-2-氰基-1-(1,3,4-三甲基吡唑-5-基)乙烯基=2,2-二甲基丙酸酯的晶体、其制备方法以及含有该晶体的悬浮液组合物。解决问题的措施是获得(E)-2-(4-叔丁基苯基)-2-氰基-1-(1,3,4-三甲基吡唑-5-基)乙烯基=2,2-二甲基丙酸酯的低熔点晶体或高熔点晶体。一种更好的保存稳定性的悬浮液组合物包括所述低熔点晶体和分散介质。
