Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors and other biologically active molecules. Its structure allows for selective functionalization, making it valuable in medicinal chemistry for building heterocyclic frameworks. 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 novel pesticides and herbicides due to its reactivity and stability in various reaction conditions.
