Description

3,3,4,4,5,5,6,6,7,7,8,8,8-Tridecafluorooctanesulphonyl Chloride is a high-value perfluorinated sulfonyl chloride derivative, serving as a critical building block for introducing perfluorooctyl sulfonyl groups into target molecules. Its primary value lies in enabling the synthesis of advanced materials with exceptional hydrophobic, oleophobic, and chemical-resistant properties. This compound is essential for R&D and production in the pharmaceutical, agrochemical, and specialty polymer industries, where surface modification and functionalization are required.

Application

• Pharmaceutical Intermediate: Key reagent for synthesizing active pharmaceutical ingredients (APIs) and prodrugs, particularly those requiring perfluoroalkyl sulfonamide or sulfonate ester functionalities.
• Agrochemical Synthesis: Used in the production of novel herbicides, fungicides, and pesticides with enhanced environmental stability and bioavailability.
• Surface Modifying Agent: Imparts permanent water- and oil-repellent (omniphobic) characteristics to textiles, coatings, and membranes.
• Polymer Functionalization: Acts as a monomer or grafting agent to create fluorinated polymers with low surface energy for applications in electronics and aerospace.
• Lithium-Ion Battery Electrolytes: Employed in the synthesis of fluorinated electrolyte additives that improve battery safety and performance.
• Chromatography Reagents: Used to derivatize compounds for enhanced detection and separation in analytical chemistry.

Quality Control

Every batch of 3,3,4,4,5,5,6,6,7,7,8,8,8-Tridecafluorooctanesulphonyl Chloride is produced and tested under a strict quality management system. We provide comprehensive analytical data to ensure product identity, purity, and consistency meet your specific research or production requirements. A Certificate of Analysis (COA) detailing purity (typically by GC or HPLC), identity confirmation (by IR and/or NMR), and other critical parameters is supplied with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and must be handled under an inert atmosphere (e.g., nitrogen or argon) to prevent decomposition. Keep away from strong bases and sources of ignition.
