Description

9-Chlorohexadecafluorononanoyl Chloride is a highly fluorinated acid chloride derivative, serving as a critical perfluorinated building block for synthesizing advanced materials. Its value lies in introducing both perfluoroalkyl chains and reactive acid chloride functionality into target molecules, enabling the creation of compounds with exceptional chemical and thermal stability, as well as unique surface properties. This intermediate is essential for R&D and production in industries focused on high-performance fluoropolymers, specialty surfactants, and surface modification agents.

Application

• Synthesis of fluorinated surfactants and emulsifiers for demanding industrial applications.
• Production of monomers for high-performance fluoropolymers with enhanced chemical resistance.
• Manufacturing of surface treatment agents to impart oil, water, and stain repellency to textiles and materials.
• Key intermediate in the pharmaceutical and agrochemical industries for creating bioactive molecules with improved metabolic stability.
• Preparation of fluorinated dyes and pigments for specialized optical applications.
• Research and development of novel materials in academic and industrial laboratories.

Quality Control

Our 9-Chlorohexadecafluorononanoyl Chloride is manufactured under stringent quality management systems. Each batch undergoes comprehensive analytical testing, including GC, NMR, and FTIR for identity and purity verification, to ensure it meets exacting standards for research and industrial synthesis. A detailed Certificate of Analysis (COA) documenting purity, assay, and impurity profiles is provided with every shipment to guarantee traceability and consistency.

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 should be kept sealed under an inert atmosphere (e.g., nitrogen or argon) when not in use to prevent hydrolysis. Recommended storage temperature is 2-8°C for long-term stability.
