Description

Trans,trans-4-Propenyl-4''-Propyl-Bicyclohexyl CAS NO 279246-65-0 is a high-purity, advanced liquid crystal intermediate characterized by its specific bicyclohexyl core with propenyl and propyl substituents. This compound is critical for fine-tuning the electro-optical properties of liquid crystal mixtures, enabling precise control over response time, viscosity, and operating temperature range. It is primarily required by manufacturers of high-performance liquid crystal displays (LCDs), optical devices, and advanced organic electronic materials where molecular uniformity and stability are paramount.

Application

• Liquid Crystal Display (LCD) Manufacturing: A key component in the formulation of nematic and chiral nematic (cholesteric) liquid crystal mixtures for televisions, monitors, and smartphones.
• Advanced Optical Shutters and Modulators: Used in light valves, tunable filters, and other devices requiring fast-switching, stable liquid crystal materials.
• Research & Development: Serves as a crucial building block for synthesizing novel liquid crystal compounds and studying structure-property relationships in academic and industrial R&D labs.
• Specialty Chemical Synthesis: An intermediate for the production of more complex liquid crystal derivatives and functional organic molecules with specific steric and electronic characteristics.
