Description

2,4,4,5,7,7,8,10,10,11,13,13,14,16,16,17,19,19,20,22,22,23,23,24,24,24-Hexacosafluoro-2,5,8,11,14,17,20-heptakis(trifluoromethyl)-3,6,9,12,15,18,21-heptaoxatetracosanoic acid fluoride is a highly fluorinated, multi-branched perfluoroether acid fluoride, distinguished by its unique molecular architecture. This compound is a critical advanced intermediate for synthesizing specialized fluorinated polymers and surfactants with exceptional chemical and thermal stability. It is essential for R&D and manufacturing in industries requiring materials with extreme hydrophobicity, oleophobicity, and resistance to harsh environments.

Application

• High-Performance Fluoropolymer Synthesis: A key monomer for creating novel perfluoropolyethers (PFPEs) and fluorinated acrylates used in specialty coatings, seals, and gaskets.
• Advanced Surface Modification: Used to manufacture fluorinated surfactants and surface treatment agents that impart oil, water, and stain repellency to textiles, electronics, and membranes.
• Specialty Additives for Lubricants: Serves as a precursor for high-temperature, chemically inert lubricant additives for aerospace, semiconductor, and precision engineering applications.
• Electronics and Semiconductor Manufacturing: Employed in the formulation of heat-resistant, dielectric coatings and etching-resistant materials for microelectronics.
• Pharmaceutical and AgroChemical Intermediates: Used in the synthesis of fluorinated bioactive molecules, where the introduction of fluorine atoms can dramatically alter metabolic stability and activity.
• Fire-Fighting Foam Concentrates (Legacy/Controlled Applications): Historically used as a precursor in certain fluorosurfactant formulations. (Note: Compliance with global PFAS regulations is essential).

Quality Control

Our production of this high-purity fluorochemical intermediate adheres to stringent quality protocols. Every batch is characterized using advanced analytical techniques including NMR (19F, 1H), FT-IR, and GC-MS/HPLC to confirm structural identity and purity. We provide comprehensive Certificates of Analysis (COA) detailing assay, moisture content, and key impurity profiles. Our quality system is designed to ensure batch-to-batch consistency and reliability for your critical synthesis processes.

Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive) and must be stored under a dry, inert atmosphere (e.g., nitrogen or argon) in a cool, dry place. Recommended storage temperature is 2-8°C for long-term stability. Keep away from moisture, strong bases, and reactive materials.
