Benzoylhydrazine is primarily used in organic synthesis as a building block for the preparation of various chemical compounds. It serves as a key intermediate in the production of pharmaceuticals, particularly in the synthesis of drugs with anti-inflammatory, antimicrobial, and anticancer properties. Additionally, it is utilized in the development of agrochemicals, including herbicides and insecticides, due to its ability to act as a precursor for active ingredients. In research, benzoylhydrazine is employed to study reaction mechanisms and to develop novel organic molecules. Its applications also extend to the field of polymer chemistry, where it is used in the synthesis of specialty polymers with specific functional properties.
