Description

cis-9-Octadecene-1-Thiol is a high-purity, long-chain alkenyl thiol characterized by its terminal thiol group and specific cis-configuration. This compound is a valuable chemical intermediate, prized for its ability to introduce thiol functionality and a long hydrocarbon chain into target molecules. It is primarily utilized in advanced material science, serving as a key building block for the synthesis of specialty polymers, surface modifiers, and ligands for metal complexes. Researchers and industrial chemists in sectors such as polymer additives, nanotechnology, and specialty chemical manufacturing rely on its consistent quality and reactivity.

Application

• Polymer Modification: Acts as a chain transfer agent or functional monomer in the synthesis of polymers with tailored properties, such as adhesion, cross-linking density, or surface energy.
• Surface Functionalization: Used to create self-assembled monolayers (SAMs) on metal surfaces (e.g., gold, silver) for applications in sensors, corrosion inhibition, and nanotechnology.
• Ligand Synthesis: Serves as a precursor for creating thiol-based ligands used in catalysis and the stabilization of metal nanoparticles.
• Lubricant & Fuel Additives: Employed in the development of extreme pressure (EP) additives and anti-wear agents due to its sulfur content and olefinic chain.
• Chemical Intermediate: A versatile building block in organic synthesis for pharmaceuticals, agrochemicals, and other fine chemicals requiring a long-chain thiol moiety.
• Cross-linking Agent: Utilized in the vulcanization of rubber or as a cross-linker in certain resin systems to enhance thermal and mechanical stability.
