Description

1,1,2,2,3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10,11,11,12,12,12-Pentacosafluorododecane-1-Sulphonic Acid is a highly fluorinated, long-chain perfluoroalkanesulfonic acid (PFSA) derivative, valued for its exceptional chemical and thermal stability combined with strong acidity. This compound is a critical precursor and intermediate in the synthesis of advanced fluorinated surfactants, polymers, and surface modifiers. It is primarily utilized by R&D chemists and industrial manufacturers in the specialty chemical, electronics, and advanced materials sectors seeking to impart unique hydrophobic, oleophobic, and low-surface-energy properties.

Application

• Fluorinated Surfactant Synthesis: A key building block for manufacturing high-performance perfluorinated anionic surfactants used in fire-fighting foams, coatings, and mist suppressants.
• Polymer Modification: Used to create sulfonated fluoropolymers with ion-exchange capabilities for applications in proton exchange membranes (PEMs) for fuel cells.
• Surface Treatment Agent: Imparts durable oil, water, and stain repellency to textiles, carpets, paper, and leather.
• Electronics Industry: Serves as an etching agent and surface tension modifier in the manufacturing of semiconductors and electronic components.
• Catalysis & Chemical Synthesis: Acts as a strong acid catalyst or a reagent in specialized organic synthesis, particularly where inert, non-nucleophilic conditions are required.
• Research & Development: An important reference standard and intermediate in environmental and analytical chemistry for studying per- and polyfluoroalkyl substances (PFAS).

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and a strong acid; ensure containers are sealed under inert atmosphere (e.g., nitrogen) after opening to prevent moisture absorption and degradation. Keep away from incompatible materials such as strong bases and oxidizing agents.
