Used primarily as a building block in organic synthesis, especially in pharmaceutical and materials research. Its alkyne and aromatic functionalities make it suitable for cross-coupling reactions, such as Sonogashira and click chemistry, enabling the construction of complex molecular architectures. Commonly employed in the development of bioactive molecules, including potential drug candidates targeting neurological and oncological pathways. Also explored in the synthesis of conjugated organic materials for electronic applications due to its rigid structure and electronic properties.
