Description

2,3,5,6-Tetrafluoro-4-Trifluoromethyl-Benzoyl Fluoride is a highly fluorinated aromatic acid fluoride derivative, serving as a critical building block in advanced synthetic chemistry. Its value lies in its unique perfluorinated structure, which imparts exceptional chemical stability, lipophilicity, and resistance to metabolic degradation, making it indispensable for creating high-performance materials and active compounds. This specialty intermediate is primarily needed by R&D and production teams in the pharmaceutical, agrochemical, and advanced materials sectors for synthesizing novel fluorinated molecules.

Application

• Pharmaceutical Intermediate: Key precursor for synthesizing active pharmaceutical ingredients (APIs) with enhanced bioavailability and metabolic stability, particularly in antiviral and anticancer drug discovery.
• Agrochemical Synthesis: Used in the production of next-generation herbicides and pesticides, where the fluorine atoms contribute to improved efficacy and environmental persistence.
• Liquid Crystal & OLED Materials: Serves as a building block for fluorinated components in electronic display materials, improving dielectric properties and thermal stability.
• Polymer & Resin Modification: Incorporated into specialty polymers (e.g., polyarylates, polyimides) to enhance chemical resistance, thermal stability, and surface properties.
• Fluorinated Surfactant & Coating Agent: Used to synthesize surfactants and surface treatment agents that provide superior oil and water repellency.
• Organic Synthesis Reagent: Acts as a versatile acylating agent in organic synthesis for introducing the perfluorinated benzoyl group into complex molecules.

Quality Control

Our 2,3,5,6-Tetrafluoro-4-Trifluoromethyl-Benzoyl Fluoride undergoes rigorous quality testing to ensure compliance with industry standards. We employ advanced analytical techniques including GC, HPLC, NMR, and FTIR to verify identity, purity, and impurity profiles. Certificates of Analysis (COA) detailing batch-specific results are available upon request, supporting your quality assurance and regulatory documentation needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). This compound is hygroscopic (moisture-sensitive) and reacts with strong bases; therefore, it must be kept under an inert atmosphere (e.g., nitrogen or argon) in a desiccated environment to prevent hydrolysis and maintain purity. Keep away from incompatible materials such as strong alkalis and oxidizing agents.
