Description

9-Chlorohexadecafluorononanoic Acid is a highly fluorinated carboxylic acid derivative, characterized by its unique perfluoroalkyl chain terminated with a chloro group. This structure makes it a valuable fluorinated intermediate and surfactant precursor, offering exceptional chemical and thermal stability alongside hydrophobic and oleophobic properties. It is primarily utilized in advanced material science, including the synthesis of specialty polymers, surface treatments, and as a key building block for high-performance fluorosurfactants and coatings in demanding industrial applications.

Application

• Fluorosurfactant Synthesis: A key raw material for manufacturing high-performance, low-surface-tension fluorosurfactants used in fire-fighting foams, coatings, and electronics.
• Polymer Modification: Serves as a functional monomer or modifier to impart oil, water, and stain resistance to polymers and resins.
• Surface Treatment Agent: Used to create hydrophobic and oleophobic surfaces on textiles, paper, leather, and optical components.
• Chemical Intermediate: An essential building block in organic synthesis for pharmaceuticals, agrochemicals, and liquid crystal materials.
• Specialty Coatings: Incorporated into formulations for non-stick, corrosion-resistant, and high-durability industrial coatings.
• Research & Development: Employed in academic and industrial R&D for studying fluorocarbon chemistry and developing novel fluorinated compounds.

Quality Control

Our 9-Chlorohexadecafluorononanoic Acid is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including chromatography and spectroscopy, to ensure high purity and consistent performance. A Certificate of Analysis (COA) detailing specific batch results is provided with every shipment to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area away from strong bases and oxidizing agents. Recommended storage temperature is between 15-25°C. Due to its nature as a strong acid/organic solvent, handle with appropriate personal protective equipment and ensure containers are kept tightly sealed to prevent moisture absorption.
