Used primarily as a specialty intermediate in organic synthesis, particularly in the development of advanced materials and pharmaceuticals. Its conjugated structure with multiple phenyl groups makes it valuable in the preparation of liquid crystals and optoelectronic materials. It also serves as a building block in the synthesis of complex polyene systems for research in stereochemistry and reaction mechanisms. Due to its hydrophobic nature and structural rigidity, it finds use in the design of novel ligands and catalysts in asymmetric synthesis.
