Description

3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10,11,11,12,12,12-Henicosafluorododecane-1-Sulphonyl Chloride is a highly fluorinated sulfonyl chloride derivative, serving as a critical building block for introducing perfluorinated chains into target molecules. This compound is valued for its ability to impart exceptional chemical resistance, thermal stability, and hydrophobic/oleophobic properties to advanced materials. It is primarily sought by R&D and production teams in the pharmaceutical, agrochemical, and specialty polymer industries for synthesizing surfactants, surface modifiers, and novel fluorinated intermediates.

Application

• Pharmaceutical Intermediate: Key reagent for synthesizing fluorinated active pharmaceutical ingredients (APIs) and prodrugs to enhance metabolic stability and bioavailability.
• Agrochemical Synthesis: Used in the production of advanced fluorinated pesticides and herbicides, improving their rainfastness and environmental persistence.
• Fluorinated Surfactant & Polymer Production: Essential for creating high-performance surfactants for fire-fighting foams (AFFF) and fluoropolymers with superior chemical and thermal resistance.
• Surface Modification Agent: Imparts durable water, oil, and stain repellency to textiles, coatings, and membranes.
• Lithium-Ion Battery Electrolyte Additive: Employed in the development of fluorinated electrolyte additives to improve battery safety and cycle life.
• Advanced Material Research: Serves as a precursor for novel fluorinated liquid crystals, ionic liquids, and nanomaterials in academic and industrial R&D.
