Description

1-Hexadecanethiol is a high-purity, long-chain alkanethiol characterized by its terminal thiol (-SH) functional group. This compound is a critical building block and surface modifier valued for its ability to form self-assembled monolayers (SAMs) on various metal surfaces, particularly gold. It is essential for manufacturers and researchers in nanotechnology, materials science, and specialty chemical synthesis who require precise surface engineering and controlled molecular interactions. Its properties make it a key reagent for creating hydrophobic coatings, corrosion inhibitors, and functionalized nanoparticles.

Application

• Surface Modification & Self-Assembled Monolayers (SAMs): Used to form ordered, single-molecule layers on gold, silver, and other metal surfaces for research and industrial applications.
• Nanoparticle Capping Agent: Acts as a stabilizer and functionalizing ligand for gold and semiconductor nanoparticles (quantum dots), controlling size, preventing aggregation, and imparting specific surface properties.
• Lubricant & Fuel Additive: Serves as an extreme pressure additive and anti-wear agent in lubricating oils and greases, and as a odorant or stabilizer in fuel formulations.
• Polymer Chemistry & Rubber Industry: Functions as a chain transfer agent in radical polymerizations to control molecular weight and as a peptizing or vulcanization agent in rubber processing.
• Corrosion Inhibition: Applied as a thin-film corrosion inhibitor for metal surfaces, providing a protective hydrophobic barrier.
• Chemical Synthesis Intermediate: Utilized in organic synthesis for the introduction of the hexadecylthio group or for the preparation of more complex thioethers and disulfides.
