Description

1,1'-Biphenyl, 4'-[(Trans,Trans)-4'-Butyl[1,1'-Bicyclohexyl]-4-Yl]-3,4-Difluoro- is a high-purity, advanced organic intermediate characterized by its complex, multi-cyclic biphenyl structure with fluorine and alkyl substituents. This compound is valued for its unique combination of molecular rigidity, thermal stability, and specific electronic properties imparted by its precise stereochemistry and fluorine atoms. It is primarily sought after by R&D and production teams in the pharmaceutical, advanced materials, and liquid crystal display (LCD) industries for synthesizing novel active ingredients and functional materials.

Application

• Liquid Crystal (LC) Materials: A key intermediate for synthesizing high-performance, fluorinated liquid crystal compounds used in advanced LCD displays, where it contributes to improved response times, wider viewing angles, and enhanced stability.
• Pharmaceutical Intermediates: Serves as a sophisticated building block in the synthesis of complex drug candidates, particularly those targeting central nervous system (CNS) disorders or requiring specific stereochemistry and lipophilicity.
• Organic Light-Emitting Diodes (OLEDs): Used in the development of novel electron-transport materials or host materials for OLED devices, leveraging its stable, conjugated biphenyl core.
• Advanced Polymer Synthesis: Acts as a monomer or cross-linking agent for creating specialty polymers with enhanced thermal, mechanical, or optical properties for high-performance engineering plastics.
• Organic Semiconductor Research: Investigated as a potential component in the development of novel organic field-effect transistors (OFETs) and photovoltaic materials due to its potential charge transport characteristics.
• Chemical Research & Development: Employed in academic and industrial labs as a model compound or a starting material for exploring new organic reactions and synthesizing complex molecular architectures.
