Description

3,5-Dichloro-4-(1,1,2,2-tetrafluoroethoxy)phenyl isocyanate is a specialized aromatic isocyanate monomer featuring a unique tetrafluoroethoxy substituent. This compound is critical for synthesizing advanced polymers and functional materials that require enhanced chemical resistance, thermal stability, and low surface energy. It is primarily utilized by R&D chemists and process engineers in the agrochemical, pharmaceutical, and high-performance polymer industries for developing novel active ingredients, intermediates, and fluorinated polyurethanes.

Application

• Agrochemical Intermediate: A key building block for the synthesis of novel herbicides and pesticides, leveraging the fluorinated side chain for improved bioavailability and environmental persistence.
• Pharmaceutical Synthesis: Used in the research and development of active pharmaceutical ingredients (APIs), particularly where the introduction of a fluorinated aromatic moiety is required for metabolic stability.
• Fluorinated Polyurethane Production: Serves as a core monomer for creating specialty polyurethane coatings, adhesives, and elastomers with superior oil, chemical, and water resistance.
• Advanced Material Research: Employed in academic and industrial R&D to develop new fluorinated polymers, liquid crystals, and functional materials for electronics and optics.
• Cross-linking Agent: Acts as a reactive cross-linker for polymers and resins, enhancing mechanical properties and durability through urethane linkages.
• Surface Modification: Used to graft fluorinated groups onto surfaces or polymers to impart hydrophobic and oleophobic characteristics.

Quality Control

Every batch of 3,5-Dichloro-4-(1,1,2,2-tetrafluoroethoxy)phenyl isocyanate undergoes rigorous analytical testing to ensure identity, purity, and consistency. Our quality assurance protocols are designed to meet the stringent requirements of research and industrial-scale synthesis. A comprehensive Certificate of Analysis (COA) detailing purity (typically by HPLC or GC), identity confirmation (by IR and/or NMR), and impurity profiles is provided with each shipment to guarantee reliable performance in your critical applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and must be kept under a dry inert atmosphere (e.g., nitrogen or argon) to prevent decomposition from moisture ingress. Keep away from heat, open flames, and incompatible materials such as alcohols, amines, and strong bases.
