Description

4-n-Octadecyloxyaniline is a high-purity, long-chain alkoxy-substituted aniline derivative, identified by CAS NO 4105-89-9. This specialty organic intermediate is valued for its unique amphiphilic structure, combining a hydrophilic aniline head with a long hydrophobic alkyl tail, which is critical for synthesizing advanced materials. It is essential for researchers and manufacturers in the fields of liquid crystal technology, organic semiconductors, and specialty surfactants who require precise molecular architecture for performance-driven applications.

Application

• Liquid Crystal (LC) Manufacturing: A key intermediate for synthesizing liquid crystal compounds used in display technologies (LCDs) and optical devices.
• Organic Electronics: Serves as a building block for organic semiconductors, charge-transport materials, and components in OLEDs and organic photovoltaics.
• Specialty Surfactants & Amphiphiles: Used to create non-ionic surfactants with specific hydrophilic-lipophilic balance (HLB) for advanced formulations.
• Polymer Science: Acts as a monomer or functionalizing agent for producing polymers with tailored surface properties and self-assembly characteristics.
• Chemical Synthesis: An important precursor in organic synthesis for introducing long alkoxy chains into complex molecules, including dyes and pharmaceuticals.
• Material Science Research: Employed in R&D for developing novel nanomaterials, Langmuir-Blodgett films, and ordered molecular assemblies.
