Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors for cancer treatment. It serves as a building block in medicinal chemistry due to its ability to undergo selective cross-coupling reactions, enabling the construction of complex heterocyclic systems. Commonly employed in research settings for designing bioactive molecules with potential anti-inflammatory, antiviral, and antitumor activities. Its halogenated structure allows for further functionalization via palladium-catalyzed reactions, making it valuable in drug discovery and development.
