Description

3,3,4,4,5,5,6,6,7,7,8,8,9,9,9-Pentadecafluoro-1-Nonanesulfonic Acid is a highly fluorinated sulfonic acid derivative, valued for its exceptional chemical and thermal stability imparted by the perfluorinated alkyl chain. This compound serves as a key building block and intermediate in the synthesis of advanced surfactants, polymers, and specialty materials. It is primarily needed by R&D laboratories and industrial manufacturers in the fluorochemical, electronics, and specialty polymer sectors.

Application

• Fluorinated Surfactant & Polymer Synthesis: A critical precursor for manufacturing high-performance, oil- and water-repellent coatings and surface modifiers.
• Catalyst & Reagent: Used as a strong acid catalyst in organic synthesis reactions, particularly where stability under harsh conditions is required.
• Electroplating & Surface Treatment: Acts as a wetting agent and additive in advanced electroplating baths for improved metal deposition and surface finish.
• Lithography & Electronics: Employed in the formulation of photoresists and etching agents for semiconductor and microelectronics fabrication.
• Fuel Cell & Battery Components: Investigated for use in proton exchange membranes (PEMs) and other components due to its ion-conducting potential.
• Specialty Chemical Intermediate: Serves as a versatile intermediate for creating other perfluorinated compounds with tailored properties.

Quality Control

Our 3,3,4,4,5,5,6,6,7,7,8,8,9,9,9-Pentadecafluoro-1-Nonanesulfonic Acid is produced under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure high purity and consistent performance. Comprehensive Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials such as strong bases and oxidizing agents. Due to its strong acid nature, containers should be kept tightly sealed and constructed of compatible materials (e.g., PTFE, fluorinated polymers) to prevent degradation. Recommended storage temperature: 2-8°C for long-term stability.
