Description

1,1,2,2,3,3,4,4,5,5,6,6,7,7,8,8,9,9,9-Nonadecafluorononane-1-Sulfonic Acid is a highly fluorinated, short-chain perfluoroalkyl sulfonic acid (PFSA) derivative, valued for its exceptional chemical and thermal stability combined with strong acidity. This compound serves as a critical building block and catalyst in advanced material science and specialty chemical synthesis, where its unique perfluorinated tail imparts hydrophobic and oleophobic properties. It is primarily sought by researchers and manufacturers in the electronics, polymer, and surface treatment industries for developing high-performance coatings, electrolytes, and surfactants.

Application

• Catalyst & Reagent: Used as a superacid catalyst in organic synthesis, particularly for reactions requiring high acidity and stability under harsh conditions, such as alkylations and acylations.
• Polymer & Material Science: Serves as a key monomer or additive for synthesizing perfluorinated ionomers and specialty polymers with enhanced chemical resistance and thermal stability.
• Surface Modification: Employed to create ultra-hydrophobic and oleophobic coatings for textiles, electronics, and membranes, providing water, oil, and stain repellency.
• Electrolyte Component: Investigated for use in advanced battery systems and fuel cells as a component of proton-conducting membranes due to its ionic properties.
• Surfactant Intermediate: Acts as a precursor for the synthesis of fluorinated surfactants and emulsifiers used in demanding industrial applications like fire-fighting foams and specialty cleaners.
• Etching & Plating: Utilized in the microelectronics industry for surface treatment and etching processes where precise chemical resistance is required.

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). Due to its nature as a strong acid/organic solvent, it should be kept away from incompatible materials such as strong bases and oxidizing agents. Ensure containers are kept upright to prevent leakage.
