Description

4-Octadecylaniline 97 is a high-purity, long-chain alkyl-substituted aniline derivative, serving as a crucial intermediate in advanced organic synthesis. Its value lies in the unique combination of a reactive primary aromatic amine group with a long hydrophobic octadecyl chain, enabling the creation of surfactants, liquid crystals, and functional polymers. This compound is essential for R&D and production in the specialty chemicals, materials science, and pharmaceutical industries, where precise molecular architecture is required.

Application

• Surfactant & Emulsifier Synthesis: Key intermediate for producing non-ionic and cationic surfactants with specific hydrophobic-lipophilic balance (HLB) properties.
• Liquid Crystal Materials: Used in the synthesis of thermotropic liquid crystals for display technologies and optical devices.
• Polymer Modification: Acts as a monomer or chain extender to introduce long alkyl side chains into polymers, modifying their solubility, thermal, and mechanical properties.
• Corrosion Inhibitor Precursor: Employed in formulating high-performance corrosion inhibitors for industrial lubricants and coatings.
• Pharmaceutical Intermediates: Serves as a building block for the synthesis of bioactive molecules and drug candidates.
• Dye & Pigment Manufacturing: Used in the production of oil-soluble dyes and specialty pigments.
• Research & Development: A valuable tool in academic and industrial research for studying self-assembly, surface chemistry, and organic reaction mechanisms.
