Description

1H,1H,2H,2H-Perfluoro-9-Methyldecyl Iodide is a high-value perfluorinated alkyl iodide building block, essential for introducing highly fluorinated segments into target molecules. This compound matters for its ability to impart exceptional hydrophobicity, oleophobicity, and chemical resistance to surfaces and materials. It is primarily needed by R&D chemists and manufacturers in the advanced materials, specialty coatings, and pharmaceutical intermediates sectors for synthesizing novel fluorinated polymers and surfactants.

Application

• Fluorinated Surfactant & Polymer Synthesis: A key intermediate for creating high-performance, low-surface-energy materials used in coatings, textiles, and electronics.
• Surface Modification Agent: Used to impart water- and oil-repellent (omniphobic) properties to various substrates, including glass, metals, and fabrics.
• Pharmaceutical & Agrochemistry Intermediates: Serves as a building block for introducing fluorinated groups into bioactive molecules to enhance metabolic stability and bioavailability.
• Lithography & Semiconductor Processing: Employed in the formulation of advanced photoresists and anti-reflective coatings for microelectronics fabrication.
• Fluorous Chemistry & Catalysis: Used in the synthesis of fluorous tags and ligands for separation science and catalyst recovery systems.
• Firefighting Foam Precursor: Acts as an intermediate in the production of certain fluorosurfactants historically used in aqueous film-forming foams (AFFF).

Quality Control

Our 1H,1H,2H,2H-Perfluoro-9-Methyldecyl Iodide is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including NMR (19F, 1H) and GC/HPLC analysis, to ensure high chemical purity and structural identity. Certificates of Analysis (COA) detailing purity, assay, and impurity profiles are provided with every shipment to support your R&D and production needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at room temperature (15-25°C). Keep away from strong acids and incompatible organic solvents. Due to its light-sensitive nature, handling should be performed under subdued light or in amber glass containers when possible.
