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 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 larger drug-like molecules. Also utilized in agrochemical research for designing novel pesticides and herbicides due to its ability to modulate biological activity in target organisms.
