Description

4,4,5,5,6,6,7,7,8,8,8-Undecafluorooctanoic Acid is a highly fluorinated, short-chain perfluorocarboxylic acid derivative. This compound is valued for its unique combination of strong acidity and high fluorine content, which imparts exceptional chemical and thermal stability. It serves as a critical intermediate and functional additive in advanced material science and specialty chemical synthesis. Key industrial users include manufacturers of fluoropolymers, surfactants, and pharmaceutical/agrochemical active ingredients.

Application

• Fluoropolymer Modification: Acts as a functional monomer or chain-transfer agent to introduce perfluoroalkyl segments, enhancing surface properties and chemical resistance of polymers.
• Specialty Surfactant Synthesis: A key precursor for manufacturing high-performance fluorosurfactants and surface treatment agents used in coatings, fire-fighting foams, and electronics.
• Pharmaceutical & Agrochemical Intermediates: Used in the synthesis of bioactive molecules where the perfluorooctyl group is required to modulate lipophilicity, metabolic stability, or membrane permeability.
• Catalyst & Ligand Preparation: Serves as a building block for creating fluorinated ligands and catalysts used in specialized organic transformations.
• Surface Functionalization: Employed to create low surface energy coatings on textiles, membranes, and electronic components for water/oil repellency.
• Analytical Chemistry & Research: Used as a standard or reagent in environmental testing for per- and polyfluoroalkyl substances (PFAS) and in academic research on fluorinated compounds.

Quality Control

Our production of 4,4,5,5,6,6,7,7,8,8,8-Undecafluorooctanoic Acid adheres to a strict quality management system. Every batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation by NMR and IR spectroscopy, to ensure it meets precise customer specifications. A comprehensive Certificate of Analysis (COA) detailing assay, impurity profile, and physical properties is provided with each shipment. We support compliance with global regulatory frameworks, including REACH.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Due to its nature as a strong acid/organic solvent, keep away from heat, ignition sources, and incompatible materials such as strong bases and oxidizing agents. Use appropriate corrosion-resistant storage materials.
