Used primarily as an intermediate in the synthesis of liquid crystal compounds, especially for display technologies. Its long alkyl chain and aromatic aldehyde functionality make it suitable for forming Schiff base or other imine linkages in liquid crystalline materials. It contributes to mesogenic properties by promoting molecular rigidity and polarity alignment. Also employed in the development of functional organic materials such as sensors and nonlinear optical substances due to its polarized electron structure and self-assembly behavior. In research, it serves as a building block for surfactants and mesogens with tailored phase transition characteristics.
