Product Name:trans-4-Ethyl-(1,1'-bicyclohexyl)-4-carboxylic acid
English Name:trans-4-Ethyl-(1,1'-bicyclohexyl)-4-carboxylic acid
CAS No.:84976-67-0
Aliases:trans-4'-Ethyl-1,1'-bicyclohexyl-4-carboxylic acid, trans-4-Ethyl-4'-carboxybicyclohexyl
Molecular Formula:C15H26O2
Physical Properties:White to off-white crystalline powder at room temperature; estimated density approx. 0.99 g/cm³, estimated boiling point approx. 360 °C at normal pressure. Slightly soluble in water; soluble in ethanol, acetone, dichloromethane, tetrahydrofuran and other organic solvents. The molecule contains a rigid trans-bicyclohexyl backbone and a carboxylic acid group, showing weak acidity and good thermal stability; it can form salts with bases.
Uses:This product is a key intermediate in the synthesis of liquid crystal materials and is used to prepare liquid crystal monomers, liquid crystal polymers, and related organic functional materials containing a bicyclohexane backbone. Its rigid trans-bicyclohexyl structure helps improve the clearing point and thermal stability of liquid crystal phases, while the carboxylic acid group allows further derivatization via esterification, acyl chlorination, and other reactions to tune the polarity, refractive index, and phase transition temperature of liquid crystal molecules.
Technical Specifications:
Purity (HPLC): ≥98.0%
Appearance: white to off-white crystalline powder
Molecular weight: 238.37
Acid value: approx. 235 mg KOH/g
Loss on drying: ≤0.5%
