Description

Perfluoro-C2-18-Alkylethyl Iodides are a homologous series of highly fluorinated organic iodides, serving as critical building blocks in advanced fluorochemical synthesis. These compounds are valued for their exceptional chemical and thermal stability, along with their ability to introduce perfluoroalkyl chains into target molecules. They are essential intermediates for manufacturers in the specialty chemical, polymer, and surface treatment industries seeking to develop materials with unique hydrophobic, oleophobic, and non-stick properties.

Application

• Fluorinated Surfactant & Polymer Synthesis: Key intermediates for producing high-performance fluorosurfactants, fluorinated acrylates, and methacrylates used in coatings, paints, and inks.
• Surface Modification Agents: Used to impart water, oil, and stain repellency to textiles, leather, paper, and non-woven fabrics.
• Pharmaceutical & Agrochemical Intermediates: Employed in the synthesis of bioactive molecules where the introduction of a perfluoroalkyl group can alter metabolic stability and lipophilicity.
• Electronic Materials: Precursors for compounds used in the formulation of specialty fluids for electronics cooling and in the manufacture of fluorinated dielectric materials.
• Firefighting Foam Concentrates (Legacy Applications): Historical use as raw materials in the synthesis of certain fluorosurfactants for aqueous film-forming foams (AFFF).
• Research & Development: Vital tools in academic and industrial R&D for exploring new fluorinated materials and their properties.

Quality Control

Our Perfluoro-C2-18-Alkylethyl Iodides are produced under stringent quality management systems. Each batch undergoes rigorous analytical testing, including Gas Chromatography (GC) and NMR spectroscopy, to ensure consistent purity, chain length distribution, and chemical identity. Certificates of Analysis (COA) detailing assay, impurity profile, and physical properties are provided with every shipment. We adhere to relevant industry standards and can support compliance documentation as required.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from heat, sparks, open flames, and strong oxidizing agents. Due to the light-sensitive nature of the material, containers should be kept in amber glass or opaque packaging.
