Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors for cancer treatment. Its structure allows for selective functionalization, making it valuable in creating active pharmaceutical ingredients (APIs) with high potency. Commonly employed in cross-coupling reactions, such as Sonogashira and Suzuki reactions, to build complex heterocyclic systems found in bioactive molecules. Also utilized in agrochemical research for designing novel pesticides with improved efficacy and environmental profiles.
