Application

This fluorinated bi(cyclohexyl) derivative serves as a key intermediate in liquid crystal formulations for advanced display technologies, particularly where high dielectric anisotropy and broad nematic phase ranges are required. The compound’s unique structure contributes to the development of low-viscosity, high-birefringence liquid crystal mixtures for fast-switching LCD applications. Researchers also utilize this material as a building block for fluorinated polymer synthesis, where its rigid biphenyl-like core enhances thermal stability while the fluorine atoms improve solubility in organic matrices. In pharmaceutical chemistry, the molecule serves as a privileged scaffold for drug discovery targeting CNS disorders due to its ability to enhance blood-brain barrier penetration.
