Used in organic synthesis as a building block for advanced functional materials, particularly in the development of conjugated polymers and liquid crystalline compounds. Its rigid terphenyl backbone and reactive ester and aldehyde functional groups allow for selective modifications, making it valuable in the preparation of molecular sensors and optoelectronic materials. Commonly employed in cross-coupling reactions and metal-organic frameworks (MOFs) due to its ability to coordinate with metal centers and form extended π-conjugated systems. Also finds use in pharmaceutical research as an intermediate in the synthesis of bioactive molecules with aromatic complexity.
