Description

3,4-Bis[(2,2,3,3,4,4,5,5,6,6,7,7,8,8,8-Pentadecafluoro-1-Oxooctyl)Amino]Benzenesulphonyl Chloride is a highly fluorinated, specialized organic intermediate featuring a reactive sulphonyl chloride group. This compound is critical for introducing perfluorinated alkyl chains and specific aromatic functionalities into target molecules, enabling the development of advanced materials with unique surface properties. It is primarily sought after by R&D chemists and process engineers in the pharmaceutical, agrochemical, and high-performance polymer industries for synthesizing novel fluorinated compounds.

Application

• Pharmaceutical Intermediate: Used in the synthesis of active pharmaceutical ingredients (APIs) where fluorination enhances metabolic stability, bioavailability, and lipophilicity.
• Agrochemical Synthesis: Serves as a key building block for creating novel herbicides, fungicides, and pesticides with improved environmental persistence and efficacy.
• Fluorinated Polymer Production: Acts as a monomer or cross-linking agent in the manufacture of specialty polymers, imparting oil, water, and stain resistance.
• Surface Modifier for Materials: Used to functionalize surfaces of textiles, membranes, and coatings to achieve superhydrophobic and oleophobic properties.
• Liquid Crystal and Electronic Material Research: Employed in the development of fluorinated components for liquid crystal displays (LCDs) and organic electronic devices.
• Specialty Surfactant and Fluorosurfactant Precursor: A critical intermediate for synthesizing high-performance surfactants used in demanding industrial applications like firefighting foams and coatings.

Quality Control

Our production of 3,4-Bis[(2,2,3,3,4,4,5,5,6,6,7,7,8,8,8-Pentadecafluoro-1-Oxooctyl)Amino]Benzenesulphonyl Chloride adheres to stringent in-process controls to ensure batch-to-batch consistency and high purity. All products undergo rigorous quality testing, including advanced chromatographic and spectroscopic methods, to ensure compliance with customer specifications and industry standards. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment.

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 (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation. Keep away from heat, sparks, open flames, and incompatible materials such as strong bases and oxidizing agents.
