This compound is primarily utilized in organic synthesis as a building block for more complex molecules. Its structure, featuring a biphenyl group and a propiolic acid moiety, makes it valuable in the development of pharmaceuticals and organic materials. It is often employed in cross-coupling reactions to create conjugated systems, which are essential in the design of organic electronic materials like semiconductors and light-emitting diodes (LEDs). Additionally, it serves as an intermediate in the synthesis of bioactive compounds, particularly those targeting inflammation or cancer, due to its ability to interact with biological targets. Its rigid biphenyl core also makes it useful in the study of molecular recognition and supramolecular chemistry.
