Used in organic synthesis as an intermediate for pharmaceuticals and fine chemicals. Its vinyl and aromatic groups enable cross-coupling reactions, making it valuable in constructing complex molecules. Commonly employed in the development of liquid crystal materials due to its rigid biphenyl core and flexible unsaturated chain. Also serves as a building block in polymer chemistry, where the double bond allows for further functionalization or polymerization. Useful in research settings for designing novel ester-based compounds with tailored physical and chemical properties.
