Description

5-Chlorooctafluoropentanoyl Fluoride is a highly fluorinated acyl fluoride derivative, serving as a critical building block in advanced chemical synthesis. Its value lies in its unique reactivity, enabling the efficient introduction of perfluorinated segments into target molecules. This compound is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and specialty materials sectors, particularly for developing compounds with enhanced stability and specific performance characteristics.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of active pharmaceutical ingredients (APIs) requiring perfluoroalkyl groups for metabolic stability or bioavailability modulation.
• Agrochemical Synthesis: Used to manufacture advanced herbicides, fungicides, and pesticides where the fluorinated moiety imparts weather resistance and biological activity.
• Fluorinated Polymer Production: Serves as a monomer or modifier in the creation of high-performance polymers with exceptional chemical, thermal, and solvent resistance.
• Liquid Crystal & Electronic Materials: Integral to producing fluorinated components for liquid crystal displays (LCDs) and dielectric materials in electronics.
• Surface Modification Reagent: Employed to impart hydrophobic and oleophobic properties to surfaces, textiles, and coatings.
• Organic Synthesis Building Block: A versatile reagent for nucleophilic acyl substitution reactions, facilitating the construction of complex fluorinated architectures in R&D.

Quality Control

Our 5-Chlorooctafluoropentanoyl Fluoride is produced under stringent quality management systems. Each batch undergoes rigorous analytical testing, including GC, NMR, and FTIR, to ensure identity, purity, and consistency. Certificates of Analysis (COA) documenting all critical parameters are available upon request, supporting your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place. Due to its hygroscopic (moisture-sensitive) nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent hydrolysis. Recommended storage temperature is 2-8°C for long-term stability. Keep away from strong acids, bases, and oxidizing agents.
