Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors for cancer treatment. Its structure supports the creation of compounds with high biological activity and selectivity. Commonly employed in medicinal chemistry for constructing complex heterocyclic systems. Also utilized in agrochemical research for developing novel pesticides due to its electron-withdrawing groups that enhance stability and reactivity. Frequently appears in Suzuki and Negishi coupling reactions to build biaryl frameworks in drug discovery.
