Used as an intermediate in the synthesis of pharmaceuticals and fine chemicals, particularly in the development of active pharmaceutical ingredients (APIs) where biphenyl structures are needed. Its aldehyde and ester functional groups allow for further chemical modifications, such as condensation or coupling reactions, making it valuable in drug discovery and organic synthesis. Commonly employed in the preparation of receptor agonists or enzyme inhibitors due to the structural rigidity and aromaticity of the biphenyl core. Also utilized in the design of specialty materials and agrochemicals requiring specific molecular frameworks.
