Description

Undecanamide, 11-Mercapto- is a specialized organosulfur compound featuring a terminal thiol group on a long-chain fatty amide backbone. This unique structure makes it a valuable intermediate for synthesizing high-performance surfactants, lubricant additives, and polymer modifiers. It is particularly sought after by R&D chemists and production engineers in the specialty chemicals, polymer, and personal care industries for introducing sulfur functionality and modifying surface properties.

Application

• Polymer Modification: Acts as a chain transfer agent or cross-linking agent in the synthesis of specialty polymers and rubbers.
• Surfactant & Detergent Intermediate: Used to produce novel anionic surfactants with enhanced wetting, emulsifying, or anti-static properties.
• Lubricant & Fuel Additive: Serves as a precursor for extreme pressure (EP) additives and anti-wear agents in industrial lubricants and functional fluids.
• Chemical Synthesis Building Block: A key intermediate for pharmaceuticals, agrochemicals, and other fine chemicals requiring a long-chain thiol functionality.
• Surface Functionalization Agent: Used to modify the surface properties of metals, polymers, or nanoparticles for improved adhesion or compatibility.
• Cosmetic & Personal Care Ingredients: Employed in the synthesis of specialty ingredients for hair care and skin care formulations.
