Used in organic synthesis as a key intermediate for the preparation of various pharmaceuticals and agrochemicals. Its ethynyl group allows for versatile reactions, such as click chemistry, enabling the creation of complex molecules. It is also employed in the development of materials for optoelectronics, including organic light-emitting diodes (OLEDs) and semiconductors, due to its ability to form stable conjugated systems. Additionally, it serves as a building block in the synthesis of biologically active compounds, particularly in the field of medicinal chemistry, where it contributes to the development of potential drug candidates targeting specific diseases.
