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 pyrazole-based drug candidates. Commonly employed in cross-coupling reactions, such as Suzuki or Heck reactions, to introduce aryl or vinyl groups, enabling the exploration of structure-activity relationships in drug design. Also utilized in agrochemical research for developing novel pesticides and herbicides due to the pyrazole moiety's inherent biological activity.
