Industrial Applications

This compound serves primarily as a high-value synthetic intermediate in the development of active pharmaceutical ingredients (APIs), crop protection agents, and advanced materials. Its orthogonal reactivity—where the iodide typically undergoes coupling first due to higher oxidative addition rates, followed by the bromide—allows for precise, stepwise construction of biaryl or heterobiaryl architectures.

  • Ideal for Suzuki, Stille, and Sonogashira cross-coupling reactions
  • Enables regioselective derivatization in multi-step syntheses
  • Used in the preparation of fluorinated bioactive molecules requiring metabolic stability
  • Compatible with palladium, nickel, and copper-based catalytic systems
