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 further functionalization, making it valuable in medicinal chemistry for constructing heterocyclic systems. Commonly employed in cross-coupling reactions, such as Suzuki or Heck reactions, to introduce the pyrazole core into target molecules. Also utilized in agrochemical research for designing new active ingredients due to its reactivity and stability.
