Description

3,3,4,4,5,5,6,6,7,7,8,8,9,9,9-Pentadecafluorononanesulphonyl Chloride is a high-value perfluorinated sulfonyl chloride intermediate, prized for its ability to introduce highly stable, hydrophobic, and oleophobic perfluoroalkyl sulfonyl groups into target molecules. This compound is essential for synthesizing advanced materials and specialty chemicals where extreme chemical resistance and low surface energy are required. It is a critical building block for R&D and production in the pharmaceutical, agrochemical, and high-performance polymer industries.

Application

• Pharmaceutical Intermediate: Key reagent for synthesizing sulfonamide drugs and other active pharmaceutical ingredients (APIs) requiring perfluoroalkyl modifications for enhanced metabolic stability and bioavailability.
• Agrochemical Synthesis: Used in the production of novel herbicides, fungicides, and pesticides, where the perfluoroalkyl chain improves rainfastness and leaf penetration.
• Polymer Modification: Serves as a monomer or grafting agent to create fluorinated polymers and copolymers with exceptional oil, water, and chemical resistance for coatings, membranes, and elastomers.
• Surface Treatment Agent: Imparts permanent water- and oil-repellent (omniphobic) properties to textiles, paper, leather, and electronic components.
• Lithography and Semiconductor Materials: A precursor for photoacid generators (PAGs) and other chemicals used in advanced photoresists for semiconductor manufacturing.
• Surfactant and Emulsifier Synthesis: Building block for creating high-performance fluorosurfactants with superior wetting and leveling properties for demanding industrial applications.
• Catalyst and Ligand Preparation: Used to synthesize specialized fluorinated ligands for catalysis in organic synthesis, particularly under harsh conditions.
• Research & Development: A versatile tool for academic and industrial R&D in medicinal chemistry, materials science, and fluorine chemistry.

Quality Control

Our 3,3,4,4,5,5,6,6,7,7,8,8,9,9,9-Pentadecafluorononanesulphonyl Chloride is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including HPLC, NMR, and titration methods, to ensure high purity and consistency. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are provided with each shipment. We can support custom purity grades to meet specific project requirements, from technical to research-grade standards.

Storage

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