Description

11-Heptylsulfanylundecanoic Acid is a specialized long-chain fatty acid derivative featuring a terminal thioether linkage. This unique molecular structure makes it a valuable intermediate for synthesizing novel surfactants, lubricant additives, and functional polymers. It is particularly sought after by research and development teams in the specialty chemicals, advanced materials, and pharmaceutical sectors for creating compounds with tailored surface-active or self-assembly properties. The compound is supplied to meet the stringent requirements of industrial and laboratory-scale applications.

Application

• Surfactant & Detergent Intermediate: Serves as a key building block for synthesizing novel anionic and nonionic surfactants with unique hydrophobic chain properties.
• Lubricant & Fuel Additive Precursor: Used in the development of extreme pressure (EP) additives and friction modifiers for advanced lubricant formulations.
• Polymer Modification: Acts as a functional monomer or chain-transfer agent for introducing long alkylthio chains into polymers to modify physical properties.
• Organic Synthesis Building Block: Employed in research for the construction of complex organic molecules, particularly those requiring a lipophilic, sulfur-containing segment.
• Surface Coating Agent: Utilized in the formulation of specialty coatings to alter surface energy and promote adhesion.
• Nanomaterial Functionalization: Applied in material science to functionalize nanoparticles or other substrates via its carboxylic acid group.
