Application

4-(4-Ethylphenyl)benzoic acid serves as a versatile building block in synthesizing liquid crystal displays (LCDs) and organic electronic materials due to its rigid biphenyl core. It is also employed in pharmaceutical research for designing nonsteroidal anti-inflammatory drug (NSAID) analogs. Additionally, its carboxyl group enables conjugation with biomolecules or metal-organic frameworks (MOFs) for advanced material engineering.
