Description

Nonafluoro-1-Butanesulfinyl Chloride is a highly fluorinated sulfinyl chloride derivative, serving as a critical building block for introducing the perfluorobutanesulfinyl (nonaflyl) group into target molecules. Its value lies in enabling the synthesis of advanced materials and specialty chemicals with enhanced properties such as thermal stability, chemical resistance, and unique surface characteristics. This reagent is essential for R&D and production in industries including pharmaceuticals, agrochemicals, and high-performance polymer manufacturing.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of novel active pharmaceutical ingredients (APIs), particularly for introducing fluorinated motifs to modulate bioavailability and metabolic stability.
• Agrochemical Synthesis: Used in creating advanced herbicides, fungicides, and insecticides where the perfluorobutylsulfinyl group contributes to weatherfastness and efficacy.
• Polymer & Material Science: Serves as a monomer or modifier for producing fluorinated polymers, coatings, and membranes with superior chemical and thermal resistance.
• Liquid Crystal & Electronic Materials: Employed in the development of fluorinated liquid crystals and electronic chemicals for display and semiconductor applications.
• Specialty Surfactants & Fluids: Building block for high-performance, fluorinated surfactants and heat-transfer fluids.
• Organic Synthesis Reagent: Versatile reagent in academic and industrial research for constructing complex sulfoxide and sulfinamide derivatives.

Quality Control

Our Nonafluoro-1-Butanesulfinyl Chloride is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including NMR, GC, and titration methods, to ensure high purity and consistency. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and light-sensitive; containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent degradation. Keep away from heat, sparks, open flames, and incompatible materials such as strong bases and oxidizing agents.
