Description

1,1,2,2,3,3,4,4,4-Nonafluorobutylsulfinyl Isocyanate is a specialized fluorinated isocyanate monomer, a key building block for introducing perfluorobutylsulfinyl groups into advanced materials. This compound matters for its ability to impart unique surface properties, including enhanced chemical resistance, hydrophobicity, and oleophobicity, to polymers and coatings. It is primarily needed by R&D chemists and process engineers in the advanced polymer, specialty coating, and high-performance material sectors seeking to develop next-generation functional products.

Application

• Synthesis of Fluorinated Polyurethanes and Polymers: As a reactive monomer for creating polymers with exceptional chemical and solvent resistance.
• Surface Modification Agents: For grafting onto substrates to create low-surface-energy, water- and oil-repellent coatings.
• Advanced Material Research: A key intermediate in developing novel fluorinated materials for aerospace, electronics, and specialty chemical applications.
• Pharmaceutical and Agrochemical Intermediates: Used in the synthesis of bioactive molecules where fluorinated groups can alter metabolic stability and bioavailability.
• Specialty Additives: Incorporation into lubricants, sealants, and elastomers to enhance performance under extreme conditions.

Quality Control

Our 1,1,2,2,3,3,4,4,4-Nonafluorobutylsulfinyl Isocyanate is produced under stringent quality management systems. Each batch undergoes rigorous analytical testing, including assay by GC or HPLC and impurity profiling, to ensure high purity and consistency. Certificates of Analysis (COA) detailing all specifications are provided with every shipment to guarantee compliance with your research and production requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at temperatures between 2°C and 8°C (refrigerated) or as specified on the label. Due to its hygroscopic (moisture-sensitive) nature, containers must be kept sealed under a dry inert atmosphere (e.g., nitrogen or argon) to prevent degradation by moisture. Keep away from heat, sparks, and open flame.
