Description

Nonafluoropentanoic Anhydride is a high-purity fluorinated organic anhydride, a key building block for introducing perfluoropentanoate moieties into target molecules. Its value lies in enabling the synthesis of advanced materials with enhanced properties such as chemical resistance, thermal stability, and unique surface characteristics. This compound is essential for R&D and production in the pharmaceutical, agrochemical, and specialty polymer industries, where precise fluorination is required.

Application

• Pharmaceutical Intermediate: Used in the synthesis of active pharmaceutical ingredients (APIs) and prodrugs, particularly for introducing lipophilic, metabolically stable fluorinated chains.
• Agrochemical Synthesis: Serves as a key reagent for creating advanced herbicides and pesticides with improved environmental persistence and efficacy.
• Fluorinated Polymer & Surface Modifier: A critical monomer or grafting agent for producing high-performance fluoropolymers, coatings, and textiles with oil, water, and stain repellency.
• Liquid Crystal & Electronic Materials: Employed in the development of fluorinated liquid crystals and dielectric materials for displays and electronic applications.
• Analytical Chemistry & Derivatization: Acts as a derivatization agent in gas chromatography and mass spectrometry for analyzing compounds containing active hydrogens.
• Specialty Surfactant & Lubricant Production: Used to synthesize fluorinated surfactants and lubricants for demanding industrial and aerospace applications.

Quality Control

Our Nonafluoropentanoic Anhydride is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including NMR, GC, and FTIR, to ensure high chemical purity and identity. Certificates of Analysis (COA) detailing purity, assay, and impurity profiles are provided with every shipment. We adhere to cGMP principles where applicable to support our customers in regulated industries.

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). This product is hygroscopic (moisture-sensitive) and must be kept under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent hydrolysis. Keep away from strong bases and moisture.
