Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of selective serotonin reuptake inhibitors (SSRIs) and other central nervous system agents. It serves as a building block in agrochemicals for creating herbicides and fungicides due to its reactive nitrile and bromo groups, which allow for further functionalization. Commonly employed in cross-coupling reactions such as Suzuki and Heck reactions to form carbon-carbon bonds in complex organic molecules. Also utilized in the preparation of liquid crystals and organic semiconductors for electronic applications.
