Used as a key intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of fluorinated organic compounds. Its reactive ethynyl and bromo groups allow for selective cross-coupling reactions, making it valuable in constructing complex molecules via Sonogashira, Suzuki, or Heck reactions. Commonly employed in medicinal chemistry for creating analogs with enhanced metabolic stability and binding affinity. Also utilized in materials science for designing conjugated systems in organic electronics.
