Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and antiviral agents. 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 the pyrazole core into larger drug-like structures. Also utilized in agrochemical research for designing novel pesticides and herbicides due to its heterocyclic stability and reactivity.
