Description

Octadecafluoro-9-(trifluoromethyl)decanoyl fluoride is a highly fluorinated, reactive acyl fluoride derivative. This compound serves as a critical fluorochemical building block for introducing perfluoroalkyl segments with a branched chain structure, enabling the synthesis of advanced materials with unique surface properties. It is essential for R&D and production in industries requiring high-performance fluoropolymers, specialty surfactants, and surface modification agents.

Application

• Fluoropolymer Modification: Key intermediate for synthesizing monomers used in high-performance, chemically resistant fluoropolymers and copolymers.
• Specialty Surfactants & Coatings: Building block for creating fluorinated surfactants, leveling agents, and additives that impart oil, water, and stain repellency to coatings and textiles.
• Pharmaceutical & Agrochemical Intermediates: Used to introduce fluorinated groups into active pharmaceutical ingredients (APIs) and agrochemicals to alter metabolic stability, bioavailability, and lipophilicity.
• Surface Functionalization: Employed to create self-assembled monolayers (SAMs) or to covalently modify surfaces (e.g., silicon, glass) for low surface energy applications.
• Lithography & Electronics: Potential precursor in the fabrication of advanced photoresists and dielectric materials for the semiconductor industry.
• Fluorinated Lubricants & Greases: Intermediate in the synthesis of high-stability, inert fluorinated lubricants for extreme environments.

Quality Control

Our Octadecafluoro-9-(trifluoromethyl)decanoyl fluoride is produced under stringent quality management systems. Each batch undergoes rigorous analytical testing, including GC, 19F NMR, and FTIR, to ensure high purity and consistent performance. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are provided with every shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat and incompatible materials such as strong bases, alcohols, and water. Due to its moisture-sensitive and highly volatile nature, containers should be kept sealed under an inert atmosphere (e.g., nitrogen) when not in use. Recommended storage temperature: 2-8°C for long-term stability.
