Description

Ethane, 1,1,1-Trifluoro-2-Isocyanato- CAS NO 371-92-6 is a specialized fluorinated isocyanate monomer, a key building block for introducing trifluoromethyl and isocyanate functionalities into advanced polymers. Its primary value lies in enabling the synthesis of high-performance materials with enhanced chemical resistance, thermal stability, and unique surface properties. This compound is essential for R&D and production in industries such as advanced coatings, specialty adhesives, and high-value fluorinated polymers, where its reactive isocyanate group allows for tailored material design.

Application

• Synthesis of Fluorinated Polyurethanes (FPUs): As a core monomer for producing FPUs with superior weatherability, chemical resistance, and low surface energy for protective and release coatings.
• Advanced Adhesive Formulations: Used to create high-performance adhesives and sealants for demanding environments in aerospace, automotive, and electronics assembly.
• Surface Modification Agents: Employed to functionalize surfaces or other polymers, imparting oil- and water-repellent (omniphobic) characteristics.
• Pharmaceutical & Agrochemical Intermediates: Serves as a key synthon in the research and development of novel active ingredients that benefit from the trifluoromethyl group's metabolic stability.
• Specialty Elastomers and Resins: A critical component in the production of fluorinated rubbers and thermosetting resins for O-rings, gaskets, and composite materials.
• Optical Materials and Coatings: Contributes to the development of polymers with specific refractive indices and durability for optical lenses and fiber claddings.

Quality Control

Our Ethane, 1,1,1-Trifluoro-2-Isocyanato- is manufactured under strict quality protocols to ensure batch-to-batch consistency and high purity, typically ≥98% (GC). Quality is verified through a comprehensive suite of analytical methods including Gas Chromatography (GC), Infrared Spectroscopy (IR), and Karl Fischer titration for moisture content. A detailed Certificate of Analysis (COA) is provided with each shipment, confirming identity, purity, and impurity profiles to meet your specific R&D or production requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at temperatures between 2°C and 8°C (refrigerated) to maximize shelf-life and stability. This product is hygroscopic (moisture-sensitive) and must be handled under a dry inert atmosphere (e.g., nitrogen or argon) to prevent hydrolysis and polymerization. Keep away from heat, sparks, open flames, and strong bases.
