Description

1-Decanethiol is a high-purity, long-chain aliphatic thiol (mercaptan) with the CAS number 143-10-2, valued for its role as a versatile intermediate and surface modifier. Its primary commercial value lies in its ability to act as a chain transfer agent in polymer synthesis and to form self-assembled monolayers on metal surfaces. This product is essential for manufacturers in the polymer, nanotechnology, and specialty chemical industries seeking to control molecular weight or engineer surface properties.

Application

• As a chain transfer agent (CTA) in the production of synthetic rubbers and specialty polymers to regulate molecular weight and polydispersity.
• In the creation of self-assembled monolayers (SAMs) on gold, silver, and other metal surfaces for nanotechnology, sensor development, and corrosion inhibition.
• As a key intermediate in the synthesis of lubricant additives and fuel additives where sulfur-containing compounds are required.
• In organic synthesis as a thiol-based building block for pharmaceuticals, agrochemicals, and fine chemicals.
• For the surface functionalization of nanoparticles and quantum dots to improve dispersion and compatibility in various matrices.
• As a modifier for metal-organic frameworks (MOFs) and other porous materials to tailor adsorption properties.
