Description

Ammonium 2,2,3,3,4,4,5,5,6,6,7,7,8,8,9,9-Hexadecafluorononan-1-Oate is a fluorinated ammonium carboxylate salt, a key intermediate for introducing highly fluorinated alkyl chains into target molecules. Its value lies in the unique combination of chemical inertness, oleophobicity, and hydrophobicity imparted by the long perfluoroalkyl segment, enabling the development of advanced surface-active materials. This compound is essential for R&D and production in industries such as specialty polymers, high-performance surfactants, and advanced material coatings.

Application

• Fluorinated Surfactant & Polymer Intermediate: Acts as a crucial building block for synthesizing fluorinated surfactants, emulsifiers, and polymers with exceptional oil and water repellency.
• Surface Modification Agent: Used to create low-surface-energy coatings for textiles, electronics, and membranes, providing stain, water, and oil resistance.
• Fire-Fighting Foam Formulations (Legacy/Developing Alternatives): Serves as a precursor in the synthesis of fluorosurfactants historically used in aqueous film-forming foams (AFFF).
• Specialty Material Additive: Imparts fluorinated characteristics to adhesives, sealants, and lubricants, enhancing their chemical stability and performance.
• Pharmaceutical & Agrochemistry Research: Utilized as a synthon to incorporate fluorinated moieties into bioactive molecules, potentially altering their metabolic stability and lipophilicity.

Quality Control

Our production of Ammonium 2,2,3,3,4,4,5,5,6,6,7,7,8,8,9,9-Hexadecafluorononan-1-Oate adheres to stringent quality management protocols. Each batch undergoes rigorous analytical testing, including NMR, HPLC, and ion chromatography, to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing all specifications are provided with every shipment. We support compliance with relevant global regulatory frameworks, including REACH.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect product quality and handling properties. Keep away from strong acids and strong bases.
