The patent of cyclosulfonone expires and the domestic market will maintain a growth trend

Cyclothenone is a new compound synthesized by adding trifluoroethoxy group to sulfotrione. It is a HPPD inhibitor herbicide. The principle of cyclosulfonate herbicide is to inhibit HPPD in weeds, causing tyrosine accumulation and plastoquinone deficiency, causing weeds to lose green, fade, and tissue necrosis, and ultimately kill weeds. Compared with mesotrione, cyclosulfone has higher activity. Compared with other varieties, cyclosulfonone has broad spectrum, high efficiency, resistance to rain erosion and no residual activity.

The appearance of the original drug of cyclosulfone is beige powder, and the pure product is solid or powder. As a polymorphic original drug, the currently known crystal forms of cyclosulfonone include crystal form A, crystal form B, crystal form C, and crystal form D. Among them, crystal form D is most suitable for long-term storage of cyclosulfonone products and is different from other crystal forms. Compared with cyclic sulfonone, crystal form D cyclic sulfonone has the advantages of high melting point, good chemical stability, and low solubility.

Cyclothenone was first developed by Bayer and registered and launched in Austria in 2007. Subsequently, cyclosulfonate was approved for marketing in the United States, Hungary, Belgium, France, Germany and other countries. Since its launch, global sales of cyclosulfone have generally maintained rapid growth, with Latin America being the largest market for cyclosulfone in the world. Cyclothenone has excellent performance and is expected to become a strong competitor to similar products such as mesotrione and atrazine. There is considerable room for growth in the cyclosulfonone market in the future.

According to the “2022-2027 China Cyclosulfone Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center, Due to patent and process restrictions, cyclosulfonone has not been registered in China before 2021. However, the cyclosulfonone patent expired in September 2019, which provides a good opportunity for domestic companies to expand into the cyclosulfonone market. There are currently 6 domestic cyclosulfonone registration certificate numbers. The main registered companies are Shandong Hailier Chemical, Anhui Jiuyi Agricultural Co., Ltd., Shandong Weifang Runfeng Chemical, and Jiangxi Tianyu Chemical. Among them, Anhui Jiuyi Agricultural Co., Ltd. has the most registration certificate numbers. 3.

The dosage forms of cyclosulfone include emulsifiable concentrate, dissolvable agent, suspending agent and dispersible oil suspension agent. Cyclothonone can be sold as a single dose product or as a compound product. Cyclothonone has excellent compounding properties. The development of cyclosulfonone compound products can expand the control spectrum, reduce the dosage of cyclosulfonone, and also increase the dosage of cyclosulfonone. performance, broadening the appropriate period of medication. At present, the compound products of cyclosulfone mainly include cyclosulfonone + terbutylazine, cyclosulfonone + disoxazoic acid, cyclosulfonone + bromoxynil + disoxazoic acid, etc.

Industry analysts said that cyclosulfonone is broad-spectrum and highly efficient. Since its launch, the cyclosulfonone market has maintained a growth trend. Its market The growth rate is higher than other types of HPPD inhibitor herbicides. At present, the patent of cyclosulfonone has expired, and the number of companies with a global presence will further increase. With the development and launch of cyclosulfonone compound agents and the increase of new cyclosulfonone projects, the future development prospects of the cyclosulfonone market are broad.
