Description

Octadecyl 4-Chlorobenzenesulfonate is a high-purity organic sulfonate ester, a versatile chemical intermediate with a long aliphatic chain. This compound is valued for its dual functionality, combining a hydrophobic stearyl group with a reactive sulfonate ester linkage, enabling its use in specialized synthesis and material modification. It is primarily sought by manufacturers in the polymer, surfactant, and specialty chemical industries for applications requiring specific surface-active or compatibilizing properties.

Application

• As a key monomer or intermediate in the synthesis of specialized polymers and resins.
• Utilized in the production of surfactants and emulsifiers for industrial formulations.
• Acts as a surface modifier or compatibilizing agent in advanced material composites.
• Employed in research and development for creating novel organic compounds and catalysts.
• Potential use as a processing aid or additive in lubricant and coating formulations.
• Serves as a standard or reference material in analytical chemistry laboratories.
