Description

Nonafluoro-3,6-Dioxaheptanoyl Chloride is a high-purity fluorinated acid chloride derivative, serving as a critical building block for introducing perfluoropolyether (PFPE) segments into target molecules. This compound matters for its ability to impart exceptional hydrophobicity, oleophobicity, and chemical resistance to advanced materials. It is primarily needed by R&D chemists and process engineers in the pharmaceutical, agrochemical, and specialty polymer industries for synthesizing novel surfactants, surface modifiers, and functional materials.

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 rainfastness and environmental persistence.
• Polymer & Material Science: Essential monomer for creating fluorinated polyesters, polyamides, and surface-modifying additives that provide stain, oil, and water resistance.
• Surfactant & Coating Formulation: Serves as a precursor for high-performance fluorosurfactants and coating cross-linkers used in electronics, textiles, and anti-fouling applications.
• Liquid Crystal & OLED Materials: Building block for fluorinated components in electronic display technologies, contributing to improved performance and durability.
• Chemical Research & Development: A versatile reagent in organic synthesis for introducing fluoroalkylether chains, facilitating the exploration of new chemical entities.

Quality Control

Our Nonafluoro-3,6-Dioxaheptanoyl Chloride is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including GC, NMR, and titration methods, to ensure high purity and consistency. A comprehensive Certificate of Analysis (COA) detailing identity, assay, and impurity profiles is provided with every shipment to support 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 at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and reacts vigorously with water, alcohols, and strong bases. Keep the container tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent degradation from moisture and to maintain product integrity.
