Description

3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10,10-Heptadecafluorodecanesulphonyl Chloride is a high-value perfluorinated sulfonyl chloride intermediate, prized for its ability to introduce highly fluorinated, hydrophobic, and oleophobic segments into target molecules. This compound is essential for synthesizing advanced materials with exceptional chemical resistance, low surface energy, and thermal stability. It is primarily sought by R&D and production teams in the pharmaceutical, agrochemical, and specialty polymer industries for creating novel surfactants, surface modifiers, and bioactive compounds.

Application

• Pharmaceutical Intermediate: Key building block for synthesizing novel active pharmaceutical ingredients (APIs) and prodrugs, particularly those requiring enhanced membrane permeability and metabolic stability.
• Agrochemical Synthesis: Used in the production of advanced herbicides, fungicides, and pesticides where fluorination improves efficacy and environmental persistence.
• Fluorinated Surfactant & Polymer Production: Serves as a critical monomer for creating perfluoropolyether (PFPE)-based surfactants, coatings, and high-performance polymers for electronics and aerospace.
• Surface Modification Agent: Imparts permanent oil-, water-, and stain-repellent properties to textiles, paper, and membranes.
• Lithography & Semiconductor Materials: Employed in the synthesis of photoresists and anti-reflective coatings for advanced semiconductor manufacturing nodes.
• Specialty Chemical Intermediate: Versatile precursor for further derivatization into sulfonamides, sulfonate esters, and other functionalized fluorochemicals for research and industrial applications.

Quality Control

Every batch of 3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10,10-Heptadecafluorodecanesulphonyl Chloride is manufactured and tested under a strict quality management system. We provide comprehensive analytical documentation, including a Certificate of Analysis (COA) detailing purity, identity, and impurity profiles via validated methods (NMR, HPLC, GC). Our quality commitment ensures material consistency for your critical synthesis and development processes.

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 bases and incompatible materials.
