Description

Benzoyl Fluoride, 3-Cyano- (9Ci) CAS NO 77976-07-9 is a specialized fluorinated aromatic building block of significant interest in advanced organic synthesis. Its core value lies in the strategic combination of a reactive benzoyl fluoride group and a cyano substituent, enabling precise molecular construction. This compound is primarily needed by research and development chemists and process engineers in the pharmaceutical and agrochemical industries for creating novel active ingredients and functional materials.

Application

• Pharmaceutical Intermediate: A key precursor in the synthesis of complex drug molecules, particularly those requiring fluorinated aromatic scaffolds for enhanced metabolic stability and bioavailability.
• Agrochemical Synthesis: Used in the development of advanced herbicides, fungicides, and insecticides where the cyano and fluorine groups contribute to biological activity and environmental persistence profiles.
• Liquid Crystal & OLED Material Research: Serves as a building block for fluorinated and cyano-substituted aromatic cores in electronic and photonic materials.
• Polymer Modification: Employed to introduce fluorinated benzoate groups into polymer chains, altering surface properties, chemical resistance, and thermal stability.
• Cross-Coupling Reactions: The benzoyl fluoride moiety can act as an electrophile in palladium-catalyzed cross-coupling reactions for carbon-carbon bond formation.
• Fluorination Reagent Precursor: Can be utilized to generate other fluorinating agents or to transfer the benzoyl group under mild conditions in synthetic pathways.

Quality Control

Our Benzoyl Fluoride, 3-Cyano- is produced under stringent quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation by FT-IR and NMR spectroscopy, to ensure it meets the high standards required for research and process chemistry. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent decomposition. Keep away from strong bases and oxidizing agents.
