Description

4-Cyano-4'-Pentyl-D11-Diphenyl CAS NO 57078-20-3 is a deuterated liquid crystal intermediate, where eleven hydrogen atoms are replaced with the stable isotope deuterium. This deuteration is critical for enhancing the performance and stability of advanced liquid crystal mixtures used in display technologies. It is an essential high-purity building block for manufacturers in the electronics and advanced materials sectors developing next-generation LCDs, OLEDs, and other electro-optical devices.

Application

• Key Intermediate for Deuterated Liquid Crystals: Serves as a fundamental component in the synthesis of high-performance, deuterated nematic and smectic liquid crystals.
• Advanced Display Manufacturing: Used in the production of liquid crystal mixtures for high-resolution, fast-response displays, including TFT-LCDs and specialized optical shutters.
• Electro-Optical Device Research: A vital material for R&D laboratories focusing on novel photonic devices, light modulators, and tunable optical filters.
• NMR Spectroscopy Standard: Can be utilized as an internal standard or reference compound in nuclear magnetic resonance (NMR) spectroscopy due to its deuterium content.
• Stable Isotope Labeling: Acts as a precursor for synthesizing other deuterium-labeled organic compounds for mechanistic studies and tracer applications.
