Benzoyl cyanide is primarily used in organic synthesis as a versatile intermediate. It is commonly employed in the production of pharmaceuticals, particularly in the synthesis of various active pharmaceutical ingredients (APIs). The compound is also utilized in the manufacture of agrochemicals, including pesticides and herbicides, where it serves as a key building block for complex molecules. Additionally, benzoyl cyanide finds application in the synthesis of dyes and pigments, contributing to the development of colorants for textiles and other materials. Its reactivity makes it valuable in research and development for creating novel organic compounds with potential industrial or medicinal uses.
