Description

4-Bromo-3,3,4,4-Tetrafluoro-1-Butene is a versatile fluorinated organic building block of significant interest in advanced chemical synthesis. Its value lies in the unique reactivity imparted by the combination of bromine and multiple fluorine atoms on a short-chain alkene, making it a critical precursor for introducing fluorinated segments. This compound is essential for R&D chemists and process developers in the pharmaceutical, agrochemical, and specialty materials sectors, where precise fluorination is required to modulate the properties of target molecules.

Application

• Pharmaceutical Intermediate: Serves as a key synthon for the introduction of tetrafluoroethylene-like units into potential active pharmaceutical ingredients (APIs), particularly in drug discovery for metabolic stability enhancement.
• Agrochemical Synthesis: Used in the development of novel herbicides and pesticides, where fluorination can improve lipophilicity and environmental persistence.
• Fluoropolymer Modification: Acts as a comonomer or grafting agent to incorporate specific functionalities into fluorinated polymers, altering surface properties or reactivity.
• Liquid Crystal & Electronic Materials: Employed in the synthesis of fluorinated components for liquid crystal displays (LCDs) and dielectric materials due to its influence on polarizability and thermal stability.
• Organic Synthesis Building Block: Utilized in cross-coupling reactions (e.g., Suzuki, Heck) and nucleophilic substitutions to construct complex, fluorinated organic architectures.
• Refrigerant & Propellant Research: Investigated as a potential intermediate or component in next-generation fluorocarbon blends with low global warming potential (GWP).

Quality Control

Our 4-Bromo-3,3,4,4-Tetrafluoro-1-Butene is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including GC, NMR, and FTIR, to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing batch-specific results are provided and available upon request, supporting your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated place, away from heat sources and incompatible materials. Due to its highly volatile nature, ensure containers are kept tightly sealed and upright to prevent leakage and concentration build-up in storage areas. Recommended storage temperature is 2-8°C for long-term stability.
