Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and other biologically active compounds. Its structure allows for selective cross-coupling reactions, making it valuable in medicinal chemistry for constructing complex molecules. Commonly employed in the preparation of antitumor, antiviral, and anti-inflammatory agents. Also utilized in agrochemical research for designing novel pesticides and herbicides due to its electron-withdrawing properties and stability.
