Used as a key intermediate in the synthesis of selective kinase inhibitors, particularly in the development of anticancer agents. Its structure allows for selective functionalization, making it valuable in medicinal chemistry for constructing complex heterocyclic systems. Commonly employed in research settings to explore new drug candidates targeting protein kinases involved in cell signaling pathways. Also utilized in the preparation of labeled compounds for biochemical assays and imaging studies due to the presence of halogen atoms that facilitate further coupling reactions.
