English description(英文原文,共 1319 字符)
Product Name:1-(4-trans-Propylcyclohexyl)-4-[4-(4-propoxyphenyl)ethynyl]benzene
English Name:1-(4-trans-Propylcyclohexyl)-4-[4-(4-propoxyphenyl)ethynyl]benzene
CAS No.:116903-49-2
Aliases:4-(trans-4-Propylcyclohexyl)-4'-propoxytolane, 1-(trans-4-Propylcyclohexyl)-2-(4-propoxyphenyl)acetylene
Molecular Formula:C26H32O
Physical Properties:White to off-white crystalline powder with liquid crystal phase; molecular weight 360.53. Insoluble in water, soluble in dichloromethane, chloroform, toluene and other organic solvents. It has a high boiling point above 400°C at atmospheric pressure and exhibits good thermal and chemical stability within the liquid crystal operating temperature range.
Uses:This product is a key intermediate for liquid crystal display materials, mainly used for the synthesis of tolane-type liquid crystal monomers or as a component of liquid crystal mixtures. The introduction of trans-cyclohexyl and alkoxy groups effectively improves the nematic phase range, response speed, and clearing point of liquid crystals, making it widely used in high-stability liquid crystal materials for TFT-LCDs.
Technical Specifications:
Assay (GC) ≥ 99.0%
Melting point: 65.0-70.0°C
Water content (Karl Fischer) ≤ 0.10%
Appearance: white or off-white crystalline powder
Residue on ignition ≤ 0.10%
