Description

3,5,7,8-Tetrachloroperfluorooctanoic Acid is a highly fluorinated and chlorinated carboxylic acid derivative, representing a specialized perfluoroalkyl substance (PFAS) with unique chemical properties. Its value lies in its role as a key synthetic intermediate and functional material, offering a combination of high stability, hydrophobicity, and oleophobicity imparted by its halogenated perfluorooctyl chain. This compound is essential for researchers and manufacturers in advanced material science, particularly for developing high-performance fluoropolymers, specialty surfactants, and surface modification agents.

Application

• Fluoropolymer Synthesis: Serves as a critical monomer or intermediate in the production of specialized fluorinated polymers and copolymers with enhanced chemical and thermal resistance.
• Specialty Surfactants & Coatings: Used to synthesize high-performance fluorosurfactants for applications requiring extreme wetting, leveling, and oil/water repellency, such as in advanced coatings and fire-fighting foams.
• Surface Modification: Acts as a precursor for creating low-surface-energy coatings on textiles, electronics, and medical devices to impart stain, water, and dirt resistance.
• Pharmaceutical & AgroChemical Intermediates: Provides a fluorinated building block for introducing perfluoroalkyl groups into more complex molecules in life science research and agrochemical development.
• Electronic Materials: Investigated for use in the formulation of dielectric fluids, etchants, or precursors for fluorinated thin films in semiconductor manufacturing.
• Research & Development: A valuable compound for academic and industrial R&D focused on the chemistry and applications of polyhalogenated perfluoroalkyl substances.

Quality Control

Our 3,5,7,8-Tetrachloroperfluorooctanoic Acid is produced and handled under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation (NMR, IR), to ensure it meets precise specifications for research and industrial use. A detailed Certificate of Analysis (COA) documenting batch-specific results is provided with every shipment to guarantee traceability and consistency.

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 nature as a strong acid/organic solvent, containers must be kept tightly sealed and constructed of compatible materials (e.g., PTFE, fluorinated polymers). Recommended long-term storage temperature is 2-8°C to maximize stability.
