Used primarily as an intermediate in the synthesis of liquid crystal materials for display technologies. It plays a key role in the production of certain pharmaceuticals and agrochemicals due to its ability to form stable aromatic ketones through acylation reactions. Commonly employed in organic synthesis to introduce biphenyl carbonyl groups into target molecules, enhancing structural rigidity and influencing biological activity. Also utilized in the preparation of specialty polymers and functional resins where thermal stability and electronic properties are important.
