Application

This compound serves as a key intermediate in synthesizing high-performance liquid crystals for display technologies, particularly in TFT-LCD applications where its trans-cyclohexyl configuration enhances response times. Researchers utilize it to develop low-viscosity LC mixtures with wide nematic phase ranges (-20°C to +120°C). Its molecular structure contributes to improved dielectric anisotropy in electro-optical devices. The compound also finds use in organic semiconductor research due to its extended π-conjugation system.
