Description

1-Butene, 3,3,4,4-Tetrafluoro- is a specialized fluorinated olefin building block, offering unique reactivity and properties due to its fluorine substitution pattern. This compound is valued for its role in introducing fluorinated segments into target molecules, which can significantly alter physical properties like chemical stability, lipophilicity, and surface activity. It is primarily sought by R&D chemists and process engineers in the pharmaceutical, agrochemical, and advanced materials sectors for synthesizing novel fluorinated intermediates and functional polymers.

Application

• Pharmaceutical Intermediate: Used in the synthesis of fluorinated active pharmaceutical ingredients (APIs) to enhance metabolic stability and membrane permeability.
• Agrochemical Synthesis: Serves as a key building block for creating novel fluorinated pesticides and herbicides with improved efficacy and environmental profile.
• Advanced Polymer Materials: A monomer or co-monomer for producing specialty fluoropolymers with enhanced chemical resistance, thermal stability, and low surface energy.
• Organic Synthesis & Catalysis: Employed in cross-coupling reactions and as a substrate in organofluorine chemistry research to develop new synthetic methodologies.
• Surface Modification Agents: Used to create fluorinated surfaces that are hydrophobic, oleophobic, and resistant to fouling.
• Liquid Crystal & Electronic Materials: A potential precursor for fluorinated components in liquid crystal displays (LCDs) and organic electronic devices.

Quality Control

Our 1-Butene, 3,3,4,4-Tetrafluoro- is produced and handled under strict quality management protocols. Every batch undergoes rigorous analytical testing, including GC, NMR, and Karl Fischer titration, to ensure high purity and consistent performance. A comprehensive Certificate of Analysis (COA) detailing identity, 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. Due to its highly volatile nature, store in a cool, well-ventilated area, ideally at 2-8°C or as specified on the label. Keep away from strong bases and fluorides. For long-term storage, consider keeping under an inert atmosphere to maintain purity.
