Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and antiviral agents. Its structure allows for easy functionalization, making it valuable in medicinal chemistry for building pyrazole-based bioactive molecules. Commonly employed in cross-coupling reactions, such as Suzuki or Heck reactions, to introduce aryl or vinyl groups, enabling the creation of diverse compound libraries for drug discovery. Also utilized in agrochemical research for designing novel pesticides with improved activity and selectivity.
