Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors, antiviral agents, antimicrobials, and anti-inflammatory drugs. Its structure allows for selective functionalization, making it valuable in medicinal chemistry for building bioactive molecules. Commonly employed in cross-coupling reactions, such as Suzuki or Heck reactions, to introduce aryl or vinyl groups, enabling the creation of complex heterocyclic compounds. Also utilized in agrochemical research for designing novel pesticides and herbicides due to its reactivity and stability in various synthetic pathways.
