This compound is primarily utilized in pharmaceutical research and development, particularly in the synthesis of active pharmaceutical ingredients (APIs). Its structure, featuring an ethynyl group and a fluorine atom, makes it a valuable building block for creating complex molecules with potential therapeutic properties. It is often employed in cross-coupling reactions, such as Sonogashira or Suzuki reactions, to introduce the ethynyl moiety into drug candidates. Additionally, its fluorine atom can enhance the metabolic stability and bioavailability of the resulting compounds, making it useful in the design of drugs targeting neurological disorders, cancer, or infectious diseases. Researchers also explore its application in material science, particularly in the development of organic semiconductors or advanced polymers, due to its unique electronic properties.
