Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and antiviral agents. Its structure allows for selective functionalization, making it valuable in constructing complex heterocyclic systems found in bioactive molecules. Commonly employed in medicinal chemistry for lead optimization due to its ability to enhance binding affinity and metabolic stability in drug candidates. Also utilized in agrochemical research for designing new pesticides with improved efficacy and selectivity.
