Description

3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10,11,11,11-Nonadecafluoroundecane-1-Sulphonyl Chloride CAS NO 65702-24-1 is a highly fluorinated sulfonyl chloride derivative, serving as a critical building block for introducing perfluorinated alkyl chains with reactive sulfonyl functionality. This compound is valued for its ability to impart exceptional chemical resistance, thermal stability, and hydrophobic/oleophobic properties to advanced materials. It is primarily sought by R&D and production teams in the pharmaceutical, agrochemical, and specialty polymer industries for synthesizing surfactants, surface modifiers, and novel fluorinated intermediates.

Application

• Pharmaceutical Intermediate: Key reagent for synthesizing fluorinated active pharmaceutical ingredients (APIs) and prodrugs, enhancing metabolic stability and bioavailability.
• Agrochemical Synthesis: Used to create advanced fluorinated pesticides and herbicides with improved environmental persistence and efficacy.
• Fluorinated Surfactant & Polymer Production: Acts as a monomer or modifier for producing high-performance materials with oil, water, and stain resistance for coatings and textiles.
• Surface Modification Agent: Imparts low surface energy and release properties to materials for applications in non-stick coatings and microelectronics.
• Lithium-Ion Battery Electrolyte Additive: Potential use in formulating advanced electrolytes to improve battery safety and performance at high voltages.
• Specialty Chemical Research: A versatile reagent in organic synthesis for constructing complex molecules with tailored fluorinated segments.

Quality Control

Our 3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10,11,11,11-Nonadecafluoroundecane-1-Sulphonyl Chloride is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and FT-IR, to ensure high purity and consistent performance. Certificates of Analysis (COA) detailing identity, purity, and impurity profiles are 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 a controlled room temperature (15-25°C). Due to its hygroscopic and moisture-sensitive nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent hydrolysis. Keep away from strong acids, bases, and oxidizing agents.
