Used primarily in organic synthesis, this compound serves as a key intermediate in the development of pharmaceuticals, particularly in the creation of active pharmaceutical ingredients (APIs). Its ethynyl group allows for versatile chemical reactions, such as Sonogashira coupling, enabling the construction of complex molecular structures. The presence of the fluorine atom enhances the biological activity and metabolic stability of the resulting compounds, making it valuable in drug discovery for conditions like cancer, inflammation, and infectious diseases. Additionally, it is employed in materials science for the synthesis of advanced polymers and specialty chemicals with unique electronic or optical properties.
