Description

7H-Dodecafluoroheptanoic Acid is a highly fluorinated, medium-chain carboxylic acid characterized by its strong acidity and excellent chemical stability. This compound is a critical building block and intermediate in the synthesis of advanced fluorinated materials, offering unique properties derived from its perfluoroalkyl segment. It is primarily utilized by manufacturers in the pharmaceutical, agrochemical, and specialty polymer industries for applications requiring enhanced surface activity, chemical resistance, or bioactivity.

Application

• Pharmaceutical Intermediate: Serves as a key precursor in the synthesis of fluorinated active pharmaceutical ingredients (APIs) and diagnostic agents.
• Agrochemical Synthesis: Used to create fluorinated pesticides and herbicides, where the fluorine atoms enhance biological activity and environmental persistence.
• Fluorinated Surfactant & Polymer Production: Acts as a monomer or modifier in the manufacture of high-performance fluorosurfactants, coatings, and elastomers.
• Surface Treatment Agent: Imparts oil, water, and stain repellency to textiles, carpets, and paper products.
• Electronics Industry: Employed in the formulation of specialty etchants and cleaning solutions for semiconductor manufacturing.
• Research & Development: A valuable reagent in organic and medicinal chemistry for introducing perfluoroalkyl groups into target molecules.

Quality Control

Our 7H-Dodecafluoroheptanoic Acid is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including assay by titration, identification by FT-IR, and quantification of key impurities by GC or HPLC, to ensure it meets precise customer specifications. A comprehensive Certificate of Analysis (COA) detailing purity, physical properties, and test results is provided with every shipment.

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. Recommended storage temperature is between 15°C and 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 and volatilization.
