Description

2,2,3,3,4,4,5,5,6,6,7,7-Dodecafluoroheptyl-Benzenesulfonate is a highly fluorinated organic sulfonate ester, a specialty chemical designed to impart unique surface-active and hydrophobic properties. This compound matters for its ability to dramatically lower surface tension and provide exceptional chemical and thermal stability in demanding formulations. Industrial R&D and production teams in advanced materials and specialty chemical synthesis need it to develop high-performance surfactants, coatings, and fluorinated intermediates.

Application

• Fluorinated Surfactant Intermediate: A key building block for synthesizing next-generation fluorosurfactants used in fire-fighting foams (AFFF), coatings, and electronics.
• Water & Oil Repellent Treatments: Imparts durable hydrophobic and oleophobic properties to textiles, leather, paper, and non-woven fabrics.
• Specialty Polymer Modification: Used as a monomer or additive to incorporate fluorinated segments into polymers, enhancing their chemical resistance and surface characteristics.
• Lithium-Ion Battery Electrolytes: Investigated as a potential electrolyte additive or co-solvent to improve battery safety and performance at high voltages.
• Advanced Coating Formulations: Enhances the leveling, wetting, and anti-fouling properties of high-performance industrial and marine coatings.
• Pharmaceutical & AgroChemical Intermediates: Serves as a fluorinated synthon in the research and development of novel active ingredients.
