Main uses: Used in organic synthesis. Pesticide intermediate; an important intermediate for the third-generation veterinary cephalosporin drug ceftiofur; an intermediate in many organic chemical productions, mainly used in the synthesis of sulfadiazine drugs and the production of insecticides, fungicides, and herbicides. As an acylating agent, it is more effective than furoic acid. Additionally, it is used in the production of new pesticides such as acaricides, miticides, and herbicides.
