Used as an intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of active ingredients requiring biphenyl scaffolds. Its aldehyde functional group allows for easy modification in multi-step organic reactions, making it valuable in creating complex molecules. Commonly employed in the production of liquid crystals and specialty polymers due to its rigid aromatic structure and ability to influence molecular alignment. Also utilized in research settings for the design of novel organic compounds with targeted biological activity.
