Used primarily as a high-performance liquid crystal intermediate in the production of advanced liquid crystal displays (LCDs). Its rigid biphenyl structure and isopropyl substitutions enhance thermal stability and mesophase behavior, making it suitable for wide-temperature-range liquid crystal formulations. Also investigated as a building block in organic semiconductors and optoelectronic materials due to its favorable electronic properties and molecular planarity. Additionally, serves as a specialty solvent and stabilizer in high-temperature reaction systems where oxidative and thermal resistance are required.
