Description

4-Pentylphenyl-4'-trans-Propylcyclohexylbenzoate is a high-purity liquid crystal monomer and a key intermediate in the synthesis of advanced liquid crystal mixtures. This compound matters for its ability to impart specific electro-optical properties, such as a broad nematic range and stable dielectric anisotropy, which are critical for display performance. It is primarily needed by manufacturers of liquid crystal displays (LCDs), optical films, and advanced electro-optic devices who require reliable, high-quality intermediates to ensure the consistency and performance of their final products.

Application

• As a core monomer in the formulation of nematic liquid crystal mixtures for Twisted Nematic (TN) and Super Twisted Nematic (STN) displays.
• As a component in ferroelectric and antiferroelectric liquid crystal (FLC/AFLC) mixtures for fast-switching applications.
• As a chiral dopant or additive to modify the pitch and helical twisting power (HTP) in cholesteric liquid crystals.
• In the research and development of advanced optical shutters, light modulators, and tunable lenses.
• As a standard or reference material for quality control and analytical testing within liquid crystal manufacturing.
• In the synthesis of more complex liquid crystal polymers and elastomers for specialized applications.

Quality Control

Our 4-Pentylphenyl-4'-trans-Propylcyclohexylbenzoate is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including HPLC, GC, and NMR, to ensure high chemical purity and isomeric consistency. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are provided with each shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); ensure the container is kept tightly sealed to prevent absorption of atmospheric moisture.
