Description

Perfluorooctanesulphonyl Chloride is a key fluorinated organic intermediate characterized by its highly reactive sulphonyl chloride group attached to a perfluorinated carbon chain. This compound is essential for introducing the unique properties of perfluoroalkyl chains—such as extreme hydrophobicity, oleophobicity, and chemical stability—into target molecules. It is primarily sought by R&D chemists and process engineers in the pharmaceutical, agrochemical, and specialty materials sectors for synthesizing surfactants, polymers, and active pharmaceutical ingredients.

Application

• Synthesis of Perfluorooctanesulfonamide Derivatives: A crucial precursor for producing surfactants and surface treatment agents used in fire-fighting foams, coatings, and textile finishes.
• Pharmaceutical Intermediate: Used in the research and development of fluorinated drug candidates to enhance metabolic stability and membrane permeability.
• Agrochemical Manufacturing: Serves as a building block for creating fluorinated pesticides and herbicides with improved environmental persistence and efficacy.
• Polymer Modification: Employed to graft perfluoroalkyl groups onto polymers, imparting oil, water, and stain resistance to advanced materials.
• Lithium-Ion Battery Electrolyte Additives: Investigated for use in formulating electrolytes to improve battery performance and safety.
• Production of Photoacid Generators (PAGs): Acts as a key raw material in the semiconductor industry for manufacturing photoresists used in advanced lithography.

Quality Control

Our Perfluorooctanesulphonyl Chloride is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including GC, HPLC, and NMR, to ensure high purity and consistency. A comprehensive Certificate of Analysis (COA) detailing identity, assay, and impurity profiles is provided with each 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 nature as a strong acid/organic solvent and high volatility, keep away from heat, sparks, and open flames. Isolate from incompatible materials such as strong bases, amines, and alcohols.
