Abstract
A tebuconazole polymorph and a preparation method therefor are described. In particular, a polymorph of (RS)-1-(4-chloropheny)-4,4-dimethyl-3-(1H-1,2,4-triazol-1-ylmethyl) pentan-3-ol, a preparation method therefor and use thereof are provided. The tebuconazole polymorph has a high purity and excellent crystallization properties, is stable under high humidity, high temperature and light conditions, has excellent solubility, and has high processing properties for formulations, high biological activities and good sterilization effects. The preparation method is simple, has stable processes, and can be implemented on a large scale. The polymorph can greatly improve the quality control and industrial application of tebuconazole-containing pesticides.
