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 functionalization at multiple sites, making it valuable in medicinal chemistry for building complex heterocyclic systems. Commonly employed in the preparation of pyrazole-containing drug candidates targeting inflammation, cancer, and central nervous system disorders. Also utilized in agrochemical research for designing new pesticides and herbicides due to its stability and reactivity in coupling reactions.
