Used as an intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the production of biphenyl-based compounds with biological activity. It serves as a building block in organic reactions, such as cross-coupling and condensation reactions, to form more complex aromatic structures. Commonly employed in the development of liquid crystals and organic semiconductors due to its rigid biphenyl framework. Also utilized in the preparation of fragrances and flavoring agents where aromatic aldehyde functionality is required.
