Description

1H,1H,2H,2H-Perfluoro-1-Decanol CAS NO 678-39-7 is a high-value fluorinated alcohol characterized by its unique combination of a hydrophobic perfluorinated chain and a reactive hydroxyl group. This structure is critical for imparting exceptional oil and water repellency, chemical resistance, and surface tension reduction properties to materials. It is an essential intermediate for manufacturers in the coatings, surfactants, and specialty polymer industries, where performance under extreme conditions is required.

Application

• Fluorinated Surfactant & Additive Synthesis: A key building block for creating high-performance surfactants used in fire-fighting foams, coatings, and electronics.
• Surface Modification & Textile Treatment: Imparts durable oil, water, and stain repellency to fabrics, leather, and non-woven materials.
• Specialty Polymer Production: Used as a monomer or modifier in fluoropolymers and acrylates to enhance chemical resistance, weatherability, and low surface energy.
• Coating & Ink Formulations: Improves leveling, wetting, and anti-cratering properties in high-performance industrial and architectural coatings.
• Electronics & Semiconductor Industry: Employed in the formulation of anti-reflective coatings, photoresists, and cleaning agents.
• Pharmaceutical & Agrochemical Intermediates: Serves as a precursor for introducing fluorinated segments into bioactive molecules to alter their metabolic stability and lipophilicity.

Quality Control

Our 1H,1H,2H,2H-Perfluoro-1-Decanol is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing, including GC, HPLC, and NMR, to ensure high purity and consistent performance. A comprehensive Certificate of Analysis (COA) detailing identity, assay, and impurity profiles is provided with each shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area. Due to its hygroscopic nature, the container should be kept tightly sealed after each use to prevent moisture absorption. Recommended storage temperature is 2-8°C for long-term stability.
