Description

1-Dokosanethiol is a high-purity, long-chain alkanethiol with the CAS registry number 7773-83-3, serving as a critical building block and surface modifier in advanced material synthesis. Its primary value lies in its ability to form self-assembled monolayers (SAMs) on various substrates, imparting specific surface properties such as hydrophobicity, corrosion resistance, and biocompatibility. This compound is essential for R&D and production in nanotechnology, specialty polymers, and electronics, where precise surface engineering is required.

Application

• Surface Modification Agent: Used to create self-assembled monolayers (SAMs) on gold, silver, and other metal surfaces for corrosion inhibition and controlled wettability.
• Polymer Chemistry: Acts as a chain transfer agent (CTA) in controlled radical polymerization (e.g., RAFT) to synthesize polymers with tailored molecular weights and architectures.
• Nanoparticle Capping Ligand: Stabilizes metal and semiconductor nanoparticles (quantum dots) to prevent aggregation and control surface chemistry.
• Lubricant Additive: Functions as an extreme pressure (EP) and anti-wear additive in advanced lubricant formulations.
• Chemical Intermediate: Serves as a precursor for synthesizing more complex sulfur-containing compounds and surfactants.
• Adhesion Promotion: Improves the adhesion between organic coatings and inorganic substrates in composite materials.
