Description

5H-Octafluoropentanoyl Fluoride is a highly reactive perfluorinated acyl fluoride intermediate. This compound is valued for its ability to introduce perfluorinated pentanoyl groups into target molecules, enabling the synthesis of advanced materials with unique properties. It is primarily sought by R&D and production chemists in the pharmaceutical, agrochemical, and specialty polymer industries for creating fluorinated compounds with enhanced stability and performance.

Application

• Pharmaceutical Intermediate: Key building block for synthesizing active pharmaceutical ingredients (APIs) with fluorinated motifs to improve metabolic stability and bioavailability.
• Agrochemical Synthesis: Used in the production of advanced herbicides and pesticides where fluorine incorporation enhances efficacy and environmental persistence.
• Fluoropolymer Modification: Serves as a grafting agent or co-monomer to introduce perfluorinated side chains, enhancing surface properties, chemical resistance, and hydrophobicity of polymers.
• Liquid Crystal & OLED Materials: Employed in the synthesis of fluorinated components for electronic display materials, improving dielectric anisotropy and performance.
• Surfactant & Coating Precursor: Acts as a starting material for manufacturing high-performance fluorosurfactants and water/oil repellent coatings.
• Organic Synthesis Reagent: A versatile reagent for nucleophilic acyl substitution reactions in complex organic synthesis, particularly where perfluorinated chains are required.

Quality Control

Every batch of 5H-Octafluoropentanoyl Fluoride is produced and tested under strict quality management systems. We ensure compliance with relevant industry standards for high-purity fluorochemical intermediates. A comprehensive Certificate of Analysis (COA), detailing purity, identity, and impurity profiles, is provided with each shipment to guarantee consistent quality and traceability for your critical processes.

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, alcohols, and amines. Due to its hygroscopic and moisture-sensitive nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent hydrolysis. Recommended storage temperature: 2-8°C for long-term stability.
