Description

Potassium 2,2,3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10,11,11-icosafluoroundecanoate is a highly fluorinated potassium carboxylate salt, a key building block for advanced fluorinated materials. Its value lies in its ability to impart exceptional chemical resistance, thermal stability, and low surface energy to polymers and surface treatments. This compound is essential for manufacturers in the specialty polymer, electronics, and high-performance coatings industries seeking to develop next-generation fluorinated products.

Application

• Fluoropolymer Synthesis: Acts as a reactive monomer or surfactant in the emulsion polymerization of fluorinated elastomers (FKM) and plastics like PTFE, PCTFE, and PFA.
• Surface Modification Agents: Used to create ultra-hydrophobic and oleophobic coatings for textiles, optics, and electronic components.
• Fire-Fighting Foams (Legacy/Formulation Studies): Serves as a precursor or reference standard in the research and analysis of per- and polyfluoroalkyl substances (PFAS).
• Lithium-Ion Battery Electrolytes: Investigated as a potential additive or salt to enhance electrolyte stability and performance in high-voltage battery systems.
• Pharmaceutical & AgroChemical Intermediates: Used in the synthesis of fluorinated active pharmaceutical ingredients (APIs) and agrochemicals to modify bioavailability and metabolic stability.
• Specialty Surfactants & Leveling Agents: Functions as a critical raw material for manufacturing high-performance fluorosurfactants used in coatings, inks, and adhesives.

Quality Control

Our Potassium 2,2,3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10,11,11-icosafluoroundecanoate is produced under strict quality management systems. Each batch undergoes comprehensive analytical testing, including NMR, HPLC, and Karl Fischer titration, to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing batch-specific results are provided and can be tailored to meet specific customer or regulatory requirements.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic nature, store in a cool, dry place at a controlled room temperature (15-25°C). The container should be kept tightly sealed in a desiccated environment to prevent moisture absorption. Store away from strong acids and incompatible materials.
