Description

1H,1H,11H-Eicosafluoro-1-Undecanol CAS NO 307-70-0 is a high-value fluorinated alcohol characterized by its unique perfluoroalkyl chain, which imparts exceptional hydrophobicity, oleophobicity, and chemical stability. This compound is a critical building block for synthesizing advanced fluorinated surfactants, polymers, and surface modifiers. It is essential for industries requiring materials with low surface energy, high thermal stability, and resistance to harsh chemical environments.

Application

• Fluorinated Surfactant & Polymer Synthesis: A key intermediate for producing high-performance fluorosurfactants used in firefighting foams (AFFF), coatings, and electronics.
• Surface Treatment & Textiles: Imparts water, oil, and stain repellency to fabrics, carpets, and non-woven materials.
• Specialty Coatings & Additives: Used to formulate low-friction, anti-graffiti, and corrosion-resistant coatings for industrial and architectural applications.
• Electronics & Semiconductor Industry: Employed in the manufacture of anti-reflective coatings, photoresists, and as a surface modifier for electronic components.
• Pharmaceutical & Agrochemical Intermediates: Serves as a precursor for synthesizing fluorinated bioactive molecules with enhanced metabolic stability and membrane permeability.
• Lubricants & Greases: Acts as an additive to improve the thermal and chemical stability of high-performance lubricants.

Quality Control

Our 1H,1H,11H-Eicosafluoro-1-Undecanol is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including GC, NMR, and FTIR, to ensure high purity and consistent performance. A comprehensive Certificate of Analysis (COA) detailing identity, assay, and impurity profiles is provided with every shipment to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive). Keep the container tightly sealed under an inert atmosphere (e.g., nitrogen) to prevent moisture absorption and degradation.
