Description

Bis(4H-Octafluorobutyl) Disulfide is a specialized fluorinated organic disulfide compound. This high-value intermediate is critical for introducing perfluorobutylthio groups, which impart unique properties like enhanced hydrophobicity, oleophobicity, and chemical resistance to target molecules. It is primarily sought by R&D and production teams in the pharmaceutical, agrochemical, and advanced materials sectors for developing novel fluorinated compounds, surface modifiers, and functional polymers.

Application

• Pharmaceutical Intermediate: Used in the synthesis of fluorinated active pharmaceutical ingredients (APIs) and prodrugs to improve metabolic stability and membrane permeability.
• Agrochemical Synthesis: Serves as a key building block for creating novel fluorinated pesticides and herbicides with enhanced efficacy and environmental persistence.
• Surface Modification Agent: Imparts oil- and water-repellent (omniphobic) characteristics to textiles, coatings, and membranes.
• Polymer & Material Science: A monomer or cross-linking agent for synthesizing specialty fluoropolymers with unique thermal and chemical resistance.
• Lubricant & Additive Formulation: Used in the development of high-performance fluorinated lubricants and functional additives.
• Lithium Battery Electrolyte Additive: Investigated for use in electrolyte formulations to improve battery stability and performance at high voltages.

Quality Control

Every batch of Bis(4H-Octafluorobutyl) Disulfide is manufactured under strict quality management systems. We employ advanced analytical techniques including GC, HPLC, NMR, and FTIR to ensure identity, purity, and consistency meet the stringent requirements of our global clientele. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with each shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at room temperature (15-25°C). Keep away from strong acids and incompatible materials such as strong bases and oxidizing agents. For long-term storage, consider maintaining under an inert atmosphere (e.g., nitrogen or argon) to prevent potential degradation.
