Description

Difluoro(Fluoroformylimino) Sulfur(Iv) is a specialized fluorinated sulfur-nitrogen compound, also known as sulfur tetrafluoride imide. This high-value intermediate is critical for introducing fluorine atoms and sulfur-nitrogen functional groups into target molecules, enabling the synthesis of novel materials with enhanced properties. It is primarily sought after by research and development chemists in the pharmaceutical and advanced materials sectors for creating new active ingredients and high-performance polymers.

Application

• Pharmaceutical Intermediate: Used in the synthesis of fluorinated drug candidates, particularly in medicinal chemistry for creating molecules with improved metabolic stability and bioavailability.
• Agrochemical Synthesis: Serves as a key building block for developing novel fluorinated pesticides and herbicides with higher efficacy and environmental selectivity.
• Advanced Material Precursor: Employed in the production of specialty polymers and coatings that require sulfur-nitrogen linkages and fluorination for thermal stability and chemical resistance.
• Ligand and Catalyst Development: Utilized in organometallic chemistry to create novel ligands and catalysts for asymmetric synthesis and other specialized reactions.
• Fluorinating Agent: Acts as a selective fluorination reagent in organic synthesis to replace specific functional groups with fluorine atoms.

Quality Control

Our Difluoro(Fluoroformylimino) Sulfur(Iv) is produced under stringent conditions to ensure high purity and batch-to-batch consistency, suitable for sensitive R&D and scale-up processes. Each lot is analyzed using advanced techniques including GC, NMR (¹⁹F & ¹H), and IR spectroscopy to confirm identity and purity. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, store under an inert atmosphere (argon or nitrogen) in a cool, dry, and well-ventilated area. Recommended storage temperature is 2-8°C for long-term stability. Keep away from strong bases and moisture.
