Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) with biological activity. Its pyrazole core allows for further functionalization, making it valuable in constructing heterocyclic compounds found in medicinal chemistry. Commonly employed in the preparation of kinase inhibitors and other drug candidates targeting inflammation, cancer, and central nervous system disorders. Also utilized in agrochemical research for developing new crop protection agents due to its reactivity and ability to form complex molecules.
