Description

Perfluorohexanoyl Fluoride 98 CAS NO 355-38-4 is a high-purity perfluorinated acyl fluoride, a key reactive intermediate in advanced fluorochemical synthesis. This compound is valued for its ability to introduce the highly stable perfluorohexyl group, imparting exceptional oil, water, and stain repellency, as well as chemical and thermal resistance to final products. It is an essential building block for manufacturers in the specialty polymers, surface treatment, and pharmaceutical industries seeking to develop high-performance materials.

Application

• Fluoropolymer Modification: Serves as a critical monomer or chain-transfer agent in the synthesis of specialized fluoropolymers and fluoroelastomers with enhanced properties.
• Surface Active Agents: Used to manufacture high-performance fluorosurfactants and leveling agents for coatings, inks, and fire-fighting foams.
• Pharmaceutical & Agrochemical Intermediates: Acts as a key synthon for introducing fluorinated segments into bioactive molecules, improving their metabolic stability and lipophilicity.
• Textile & Fiber Treatment: A precursor for durable water and oil repellent (DWR) finishes applied to technical textiles, outdoor apparel, and carpets.
• Electronic Chemicals: Employed in the production of specialty fluids for electronics cooling and as a precursor for dielectric coatings.
• Perfluoropolyether (PFPE) Synthesis: A fundamental building block in the creation of high-performance PFPE lubricants and fluids for demanding aerospace and industrial applications.

Quality Control

Our Perfluorohexanoyl Fluoride is manufactured under stringent process controls to ensure batch-to-batch consistency and high purity. Every lot is analyzed to confirm identity, potency, and impurity profiles. A comprehensive Certificate of Analysis (COA) detailing purity (by GC), water content, and other critical parameters is provided with each shipment, ensuring full traceability and compliance with your quality management system requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area. Due to its highly volatile and hygroscopic (moisture-sensitive) nature, containers must be kept sealed under a dry inert atmosphere (e.g., nitrogen) when not in use to prevent hydrolysis. Recommended storage temperature is 2-8°C to maximize stability.
