Description

Ammonium 8-Chlorotetradecafluorooctanoate is a fluorinated organic salt with a unique perfluorinated carbon chain terminated by a chlorinated segment. This compound matters as a key intermediate and functional material, valued for its chemical stability, hydrophobic/oleophobic properties, and surface activity imparted by the fluorocarbon chain. It is needed by industries involved in the development of specialty surfactants, surface treatments, and high-performance polymers, particularly where resistance to harsh chemicals and environmental conditions is required.

Application

• Fluorinated Surfactant Intermediate: Serves as a critical building block for synthesizing specialized anionic fluorosurfactants used in demanding industrial applications.
• Surface Treatment Agent: Imparts oil, water, and stain repellency to textiles, carpets, and technical fabrics.
• Polymer Additive: Used as a processing aid or modifier in fluoropolymers to enhance surface properties and processing characteristics.
• Fire-Fighting Foam Formulations (Legacy/Historical): May have been investigated or used as a component in aqueous film-forming foam (AFFF) formulations for liquid fuel fires.
• Specialty Coatings: Incorporated into coatings to provide low surface energy, leading to anti-graffiti, anti-icing, or easy-clean properties.
• Chemical Synthesis: Acts as a versatile perfluorinated synthon for introducing fluorinated segments into more complex organic molecules in pharmaceutical and agrochemical research.

Quality Control

Our Ammonium 8-Chlorotetradecafluorooctanoate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure identity, purity, and consistency. Key parameters monitored include assay (by HPLC), levels of related impurities, moisture content (KF), and confirmation of ionic form. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment to ensure full traceability and compliance with your specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive). Keep the container tightly sealed in a dry environment to prevent absorption of atmospheric moisture, which may affect product quality and handling properties.
