Description

11H-Perfluoroundecanoyl Chloride is a highly fluorinated acid chloride derivative, serving as a critical building block for introducing perfluorinated alkyl chains into target molecules. Its primary value lies in enabling the synthesis of advanced fluorinated surfactants, polymers, and surface modifiers with exceptional chemical resistance, thermal stability, and low surface energy properties. This compound is essential for R&D and production in industries such as specialty coatings, electronics, and high-performance materials, where its unique perfluorinated structure imparts water, oil, and stain repellency.

Application

• Fluorinated Surfactant Synthesis: A key intermediate for manufacturing high-performance fluorosurfactants used in fire-fighting foams, coatings, and electronics.
• Polymer Modification: Used to graft perfluorinated side chains onto polymers, enhancing their chemical inertness, thermal stability, and creating low-surface-energy materials.
• Surface Treatment Agents: Employed in the production of textile, paper, and leather treatments to confer water, oil, and stain repellency.
• Pharmaceutical & Agrochemical Intermediates: Acts as a precursor for introducing fluorinated moieties into bioactive molecules to alter their metabolic stability and lipophilicity.
• Liquid Crystal & Electronic Materials: Utilized in the synthesis of fluorinated components for liquid crystal displays (LCDs) and dielectric materials.
• Specialty Coatings & Additives: Serves as a raw material for creating release coatings, anti-fouling paints, and high-performance lubricant additives.

Quality Control

Our 11H-Perfluoroundecanoyl Chloride is manufactured under strict quality protocols. Each batch undergoes rigorous analytical testing, including assay (GC/HPLC), identity confirmation (IR, NMR), and impurity profiling, to ensure high purity and consistency. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with every shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at temperatures between 2°C and 8°C (refrigerated) to maximize stability. This material is hygroscopic (moisture-sensitive) and reacts vigorously with water, alcohols, and strong bases. Keep the container tightly sealed under an inert atmosphere (e.g., nitrogen or argon) when not in use.
