Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and other bioactive molecules. Its halogen substituents allow selective cross-coupling reactions, enabling efficient construction of complex heterocyclic compounds. Commonly employed in medicinal chemistry for structure-activity relationship studies due to the tunable reactivity of bromo, fluoro, and iodo groups. Also utilized in agrochemical research for designing novel active ingredients with improved efficacy and selectivity.
