Description

Undecanoyl Chloride, 4,4,5,5,6,6,7,7,8,8,9,9,10,10,11,11,11-Heptadecafluoro- is a highly fluorinated acid chloride derivative, serving as a critical building block for introducing perfluoroalkyl segments into target molecules. Its primary value lies in enabling the synthesis of advanced materials with exceptional chemical resistance, thermal stability, and unique surface properties. This specialty intermediate is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and high-performance materials sectors, particularly for creating fluorinated surfactants, polymers, and active pharmaceutical ingredients (APIs).

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, where the perfluoroalkyl chain improves weather resistance and biological activity.
• Fluorinated Surfactant & Polymer Production: Serves as a monomer or modifier for creating high-performance fluorosurfactants, coatings, and elastomers with superior oil, water, and chemical repellency.
• Liquid Crystal & Electronic Materials: Employed in the synthesis of fluorinated liquid crystals and dielectric materials for display technologies and electronic applications.
• Surface Modification Agent: Used to graft perfluoroalkyl chains onto surfaces, imparting low surface energy characteristics for anti-fouling, anti-icing, or easy-clean applications.
• Organic Synthesis & Research: A versatile reagent in academic and industrial R&D for constructing complex fluoroorganic molecules and exploring new material properties.

Quality Control

Our Undecanoyl Chloride, 4,4,5,5,6,6,7,7,8,8,9,9,10,10,11,11,11-Heptadecafluoro- is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including assay by GC or HPLC and identity confirmation by FT-IR and NMR, to ensure high purity and consistency. Certificates of Analysis (COA) detailing all specifications are provided with every shipment. We support compliance with relevant regulatory frameworks for industrial and research applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at temperatures between 2°C and 8°C (refrigerated) or as specified on the label. This compound is hygroscopic (moisture-sensitive) and light-sensitive; containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent decomposition. Keep away from moisture, strong bases, and alcohols.
