Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of antiviral and anticancer agents. Its structure supports the construction of complex heterocyclic systems found in bioactive molecules. Commonly employed in medicinal chemistry for scaffold modification to enhance drug potency and metabolic stability. Also utilized in agrochemical research for designing new pesticides with improved efficacy. Participates in cross-coupling reactions and cycloadditions, making it valuable in combinatorial chemistry and library synthesis for drug discovery.
