Description

Perfluoroheptanoic Anhydride is a high-purity fluorinated organic compound, serving as a critical reagent for introducing perfluoroheptanoyl groups. Its primary value lies in its role as a versatile building block for synthesizing advanced fluorinated materials and specialty chemicals. This product is essential for R&D and production in the pharmaceutical, agrochemical, and advanced materials sectors, where its unique perfluorinated chain imparts valuable properties like hydrophobicity, oleophobicity, and chemical resistance.

Application

• Pharmaceutical Intermediate: Key reagent for synthesizing fluorinated active pharmaceutical ingredients (APIs) and prodrugs to enhance metabolic stability and bioavailability.
• Agrochemical Synthesis: Used in the production of advanced fluorinated pesticides and herbicides, improving their environmental persistence and efficacy.
• Surface Modification Agent: Imparts oil- and water-repellent (omniphobic) characteristics to textiles, polymers, and coatings.
• Fluorinated Polymer Production: Acts as a monomer or modifier in the synthesis of specialty fluoropolymers and elastomers with enhanced chemical and thermal resistance.
• Lithium-Ion Battery Electrolyte Additive: Used to form stable solid-electrolyte interphase (SEI) layers, improving battery cycle life and safety.
• Analytical Chemistry Reagent: Serves as a derivatization agent in gas chromatography and mass spectrometry for analyzing compounds containing active hydrogens.

Quality Control

Our Perfluoroheptanoic Anhydride is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including assay by titration and impurity profiling by GC and 19F NMR, to ensure high purity and consistency. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with every shipment to guarantee compliance with your research and production requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Due to its reactivity as a strong acid/organic solvent, keep away from moisture, strong bases, and oxidizing agents. Use appropriate corrosion-resistant handling equipment.
