Description

Heptatriacontafluoro-18-iodooctadecane is a highly fluorinated, long-chain alkyl iodide compound, distinguished by its unique combination of perfluorinated segments and a terminal iodine atom. This structure is critical for providing exceptional chemical inertness, thermal stability, and low surface energy, making it a valuable intermediate for advanced material synthesis. It is primarily sought after by R&D and production teams in the pharmaceutical, agrochemical, and specialty polymer industries for creating fluorinated surfactants, surface modifiers, and active pharmaceutical ingredients (APIs).

Application

• Fluorinated Surfactant & Polymer Synthesis: Serves as a key building block for creating high-performance, oil- and water-repellent coatings and additives.
• Pharmaceutical Intermediate: Used in the development of fluorinated drug candidates to enhance metabolic stability and bioavailability.
• Agrochemical Active Ingredients: Incorporated into the synthesis of novel pesticides and herbicides for improved rainfastness and efficacy.
• Surface Modification Agent: Imparts low surface energy and anti-fouling properties to textiles, membranes, and electronic components.
• Liquid Crystal & OLED Material Research: Acts as a precursor for fluorinated components in display and lighting technologies.
• Specialty Lubricants & Additives: Used to formulate high-stability lubricants for demanding industrial and aerospace applications.

Quality Control

Every batch of Heptatriacontafluoro-18-iodooctadecane is manufactured and tested under a strict quality management system. We provide comprehensive analytical data to ensure consistency and purity for your critical applications. A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is available for each lot upon request, supporting compliance with internal and regulatory standards.

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 and transfers should be minimized under direct light exposure.
